Pastel Impossible Space Poster

Pastel Impossible Space Poster

Use the system imagegen skill and image-generation tool. Treat every uploaded photograph as the edit source. Build a new impossible world from its structure and relationship; do not reproduce recognizable levels, characters, props, or exact compositions from an existing game.

Output contract

• Produce one independent raster poster for every uploaded photo. Never combine photos into a collage, contact sheet, comparison layout, diptych, or shared canvas.
• Use a 3:4 portrait canvas with one exact horizontal 50/50 division. Keep truthful photography in the upper half and the pastel impossible space in the lower half. Do not let either medium invade the other.
• Preserve immediate correspondence through the translated hero's silhouette, posture, proportion, direction, spatial relation, and defining structural cues.
• Use one original orthographic-isometric spatial system, two to four main pastel colors, and one small high-purity visual jump.
• Render one small Chinese poetic line and, when helpful, one much smaller English translation. Do not use years, dates, issue numbers, VOL., or large titles.
• Return every poster as a separate image. Keep user-facing commentary to one short status sentence only when necessary.

Preserve the photographic upper half

Keep the source recognizably photographic. Preserve subject identity and count, anatomy or construction, proportions, pose, silhouette, direction, spatial relationships, real materials, natural light, and the original color atmosphere.

Apply only restrained magazine- or exhibition-photography color correction. Do not redraw, vectorize, beautify, materially relight, or apply impossible geometry, pastel color blocks, typography, or graphic overlays to this region.

Crop deliberately for the upper half. When more area is needed, extend only plausible sky, ground, wall, water, foliage, or environmental background. Never stretch, warp, mirror, duplicate, or redesign the subject.

Extract the story as spatial logic

Before prompting, privately identify:

1. the one hero subject or inseparable relationship carrying recognition;
2. its decisive silhouette, posture, direction, main axis, scale, openings, and structural turns;
3. three to six identity cues that must survive architectural translation;
4. the source's key emotion or story: approach, distance, waiting, shelter, pursuit, ascent, separation, companionship, repetition, isolation, crossing, or another visible relation;
5. one path or connection logic that can embody that relation;
6. one impossible-space operation that intensifies it;
7. the ideal placement of the hero, a tiny avatar, or a source-derived focal object;
8. one Chinese poetic afterthought and optional English translation.

Do not expose this analysis or repeat the user's design brief.

Translate the subject into architecture

Use platforms, stairs, doorways, arches, bridges, corridors, towers, ramps, suspended planes, openings, and small landscape fragments to rebuild the hero's identity.

Adapt the translation:

• buildings and interiors: retain facade rhythm, openings, massing, circulation, and one iconic structural relation;
• people and animals: preserve pose, facing direction, relationship, and scale as a tiny original figure or turn the pose into a path, arch, stair, or paired platform relation;
• plants: translate branching, growth, bloom, lean, and root/ground relation into rising paths, split towers, terraces, or suspended gardens;
• objects, food, and vehicles: preserve defining contour and function through platforms, shells, portals, bridges, ramps, or moving-path geometry;
• landscapes and natural scenes: preserve horizon, terrain, water, flow, strata, distance, or weather as stepped and suspended space.

Do not merely place a normal 3D model on a platform. The source structure must determine the architecture, path, openings, and scale.

Choose one impossible operation

Use one principal paradox:

• a stair or path that connects incompatible levels;
• a bridge that changes spatial reading at a turn;
• a looped route that appears continuous across impossible faces;
• an arch or doorway linking distant or inverted zones;
• a platform that belongs to two orientations;
• a repeated structure whose scale or direction changes along one axis;
• a suspended route whose occlusion makes two spaces become one.

Keep the paradox readable and elegant. Use it to express the source story—not as a puzzle for its own sake. Avoid stacking many optical tricks, complex Escher-like density, random floating blocks, or inaccessible routes.

Compose one quiet geometric world

Use orthographic isometric projection with parallel axes, clean geometry, clear plane separation, and no lens distortion. Build one visual center and one path through the scene.

Use height differences, approach/withdrawal, connections, occlusion, isolation, repetition, and scale to carry emotion. Keep a generous clear background around the architecture.

Add only a few subordinate supports: one tiny original figure, plant, bird, light, water plane, cloud, or source-specific prop when needed. They may not become a second focal center.

Avoid realistic perspective, wide-angle view, complete city scenes, dense level design, game UI, interface icons, collectible props, multiple avatars, decorative clouds, and copied monument/palace layouts.

Present the result as a flat editorial artwork. Do not add a device screen, game screenshot frame, poster mockup, wall, desk, gallery room, or promotional campaign context.

Use a dynamic high-key pastel system

Do not directly sample the photograph's overall palette. Instead, choose two to four clear main colors according to the source theme from cream white, pale sandstone, mist pink, coral pink, soft violet, sky blue, lake cyan, mint green, and other bright transparent-feeling pastel families.

Build one coherent combination through neighboring colors and one warm/cool contrast. Use same-family value levels to separate faces and depth.

Place one small, higher-purity jump at a doorway, turn, tiny figure, key object, route junction, or focal structural plane. Choose orange-red, magenta, blue-green, bright yellow, or another sharp hue appropriate to the chosen palette.

Keep the world bright, soft, clear, and airy. Avoid dirty gray, yellowing, low-value brown, black architecture, ordinary Morandi dullness, neon overload, rainbow structures, realistic local color, gradients, and many accents.

Keep materials perfectly clean

Use smooth matte pure-color surfaces, fine crisp edges, soft even illumination, and slight ambient shadow. Separate forms through value and color rather than material variation.

The render must be clear and delicate. Avoid grain, noise, paper texture, film texture, frosting, weathering, dirt, scratches, old print, complex PBR materials, wood, stone detail, metal reflections, glass realism, glossy highlights, harsh shadows, atmospheric fog, and cinematic lighting.

Add a small Chinese afterthought

Derive one short Chinese line from the source's emotion, relationship, action, distance, or story. Keep it quiet, open-ended, and specific to the image rather than a slogan.

Place it at a page edge, corner, architecture blank, or lower quiet area. Use fine geometric type, small size, broad tracking, and ample space. Align, occlude, or lightly interweave it with one architectural axis or plane.

Add one much smaller English translation only when it improves the editorial rhythm. Keep the translation faithful and understated.

Do not use years, dates, numbers, VOL., huge type, bold headlines, advertising slogans, copied game quotes, logos, brands, signatures, pseudo-language, or watermarks.

Compile the image-edit prompt

Write one source-specific production prompt per input photo containing:

1. one independent 3:4 portrait output and the exact 50% photography / 50% impossible-space split;
2. the upper-half preservation invariants, restrained color correction, crop, and any safe background extension;
3. the lower hero, relationship, silhouette, posture, direction, main axis, scale, and three to six identity cues;
4. the exact platforms, stairs, arches, bridges, corridors, openings, suspended planes, routes, and source-to-architecture mapping;
5. the one impossible operation, its geometric construction, and how it expresses the source emotion or story;
6. the orthographic-isometric axes, height order, path, connections, occlusions, repetitions, center of gravity, one focal system, and quiet surrounding space;
7. the exact two-to-four main pastel colors, neighboring/warm-cool logic, same-family value planes, and one high-purity jump with its narrative function;
8. the clean matte material, crisp edges, even light, slight ambient shadow, and explicit absence of texture/noise/PBR;
9. the exact Chinese poetic line and optional English translation with their edge/corner/blank/axis/plane placement;
10. hard exclusions: no multi-photo layout, no altered or redrawn upper subject, no approximate split, no copied game level or character, no normal 3D model on a platform, no multiple impossible tricks, no dense city, no realistic perspective, no dark/brown palette, no ordinary gray Morandi palette, no grain, no paper/film texture, no glossy CGI, no game UI, no year/date/number/VOL., no large title, no logo, and no watermark.

Use concrete source-to-space mapping, path, paradox, palette, plane, and typography language rather than relying on adjectives such as “premium,” “Monument Valley,” “dreamy,” or “poetic.”

Inspect and correct

Review every result at full size and thumbnail size. Verify the exact split, truthful upper photography, immediate lower identity correspondence, original orthographic-isometric world, one readable impossible operation, one path, clean pastel planes, 2–4 main colors, one small jump, texture-free matte rendering, and small Chinese text.

If the scene resembles an existing game level, redesign the massing, path, figure, and palette from the source. If it looks like a normal model, make the path or platform relation genuinely impossible. If several optical tricks compete, keep only the one carrying the story. If the palette looks dull or muddy, increase lightness and clarity. If texture or realistic materials appear, remove them completely. Regenerate with one targeted correction when needed.
