Isometric Impasto Diorama Poster

Isometric Impasto Diorama Poster

Use the system imagegen skill and image-generation tool. Treat each uploaded photograph as the edit source and preserve a direct visual relationship between its photographic and reconstructed states.

Output contract

• Produce one independent raster poster for every uploaded photo. Never combine photos into a collage, contact sheet, 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 isometric impasto diorama in the lower half. Do not let either medium invade the other.
• The lower subject must read as a stable three-dimensional miniature with volume, depth, front/back relationships, and a credible point of support—not a flat picture laid over paint.
• 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 art-magazine, independent-publication, or exhibition-photography color correction. Do not redraw, vectorize, beautify, materially relight, or apply paint texture, paper grain, diagram marks, 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.

Read the source before designing

For each photograph, privately identify:

1. the single hero subject or inseparable relationship that carries recognition;
2. its defining contour, posture, direction, scale, and identity details;
3. the support plane or spatial slice that can grow naturally from the scene;
4. the subject's center of gravity, movement direction, and useful isometric orientation;
5. the few secondary natural motifs that can add depth without becoming another focal point;
6. the brightest, liveliest source color and one sunlight-like warm accent;
7. one short supported title and, only if useful, a tiny subtitle, number, or note.

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

Rebuild the hero as an isometric miniature

Translate rather than trace. Reconstruct the source hero as a refined isometric or axonometric three-dimensional entity with clear mass, planes, thickness, overlap, front/back order, and contact with the supporting field. Preserve the source's most important identity features and narrative relationship. Slightly regularize viewpoint or proportion only when needed to make the object coherent in one shared isometric space.

Adapt the miniature language to the subject:

• architecture: readable volumes, openings, roof or facade planes, and a credible ground relationship;
• people and animals: recognizable pose, gesture, direction, clothing or surface cues, balanced weight, and stable contact rather than stiff figurine anatomy;
• plants: branching or growth volume, layered foliage, and rooted emergence from the field;
• objects and vehicles: defining body shape, functional parts, orientation, and support or motion relationship;
• landscapes and natural subjects: sculpted topography, water, strata, light, or weather organized into an isometric spatial fragment.

Do not turn the subject into a generic toy, collectible figurine, plastic maquette, glossy product render, or unrelated fantasy model.

Grow a thematic impasto field

Seat the miniature on a source-specific field made from visibly thick oil paint. The field is not a rectangular pedestal or background card. Translate it into a spatial slice supported by the photo: water, ground, road, grass, shoreline, light band, shadow, path, cloud layer, or another meaningful environmental plane.

Extend the field along the chosen isometric axes. Make the subject physically interact with it through landing, embedding, crossing, emerging, reflection, ripples, cast shadow, wake, rooted growth, or a restrained local overhang. The 2D painterly field and 3D hero must share one convincing space.

Render the field with palette-knife ridges, accumulated paint, raised edges, hand-worked strokes, and relief-like passages. Clouds, water, terrain, and light may carry sculptural paint thickness. Preserve clean real-paper areas around the paint so the illusion feels like a miniature standing on oil paint that is still wet.

Compose for depth and quiet

Use diagonal isometric direction, stable weight, foreground/background depth, and large clean negative space. Place the hero at the field's meaningful node rather than automatically centering it. Let the field direct the eye and carry perspective beyond the subject.

Add at most one low-weight group of source-supported clouds, sun, plants, ripples, birds, or abstract natural forms when depth needs reinforcement. Keep these small, subordinate, and part of the same isometric logic. Do not establish a second focal center or fill the lower half with scenery.

The finished lower half should feel like miniature sculpture, thick oil paint, and real paper fused into one tactile object. Preserve a flat poster presentation: no frame, wall, desk, hands, easel, studio scene, or product mockup.

Build a bright source-derived palette

Extract the source color that best conveys the hero's energy, then raise its lightness, purity, and vitality while keeping it refined. Use abundant clean warm white as breathing room, one transparent-looking principal color family, and a very small sunlight-like warm accent.

Keep the result bright, healing, fresh, and high-key. Avoid muddy gray, dull low contrast, dark nostalgia, generalized Morandi desaturation, neon fluorescence, sugary candy colors, rainbow palettes, or synthetic plastic gloss. Let the upper photo and lower field feel related without forcing an exact color match.

Integrate restrained typography

Derive one concise title from the supported subject, place, emotion, action, or symbolic meaning. Add only a tiny subtitle, number, or micro-note when it contributes useful rhythm.

Align type with an isometric axis, impasto edge, or genuine paper gap so it belongs to the spatial composition. Keep typography fine, precise, and subordinate. Do not paste a generic title block onto the poster.

Do not invent logos, brands, years, issue numbers, coordinates, unsupported locations, long explanations, pseudo-language, signatures, 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% diorama split;
2. the upper-half preservation invariants, restrained color correction, deliberate crop, and any safe background extension;
3. the lower-half hero's identity features, pose or direction, isometric orientation, volume, center of gravity, and contact point;
4. the thematic field's source meaning, isometric shape, perspective extension, impasto edge, and physical interaction with the hero;
5. the foreground/background order, eye path, negative-space shape, and any one subordinate natural motif group;
6. the miniature's refined material treatment, the field's palette-knife relief, and the surrounding real-paper surface;
7. the exact bright source-derived principal color, warm-white breathing room, and small sunlight accent;
8. the exact short title and optional microtext with their perspective-aware placement;
9. hard exclusions: no multi-photo layout, no altered or redrawn upper subject, no approximate split, no flat lower illustration, no rectangular paint pedestal, no floating hero, no paper craft, no plastic CGI, no toy figurine, no glossy product render, no template diorama, no muddy or neon palette, no second focal point, no mockup environment, no logo, and no watermark.

Use concrete spatial, material, and interaction language rather than relying on adjectives such as “premium,” “3D,” or “healing.”

Inspect and correct

Review every result at full size and thumbnail size. Verify the exact split, truthful upper photography, immediate recognition below, coherent isometric planes, stable support, meaningful hero–paint interaction, obvious impasto relief, warm paper, bright source-derived color, and large quiet space.

If the hero looks flat, specify visible side and top planes, thickness, occlusion, and contact shadow. If it floats, strengthen its landing, embedding, reflection, roots, wake, or cast shadow. If the paint becomes a rectangle, reshape it into the source-specific spatial slice and expose irregular raised edges. If the result looks plastic or toy-like, replace glossy CGI cues with painterly sculptural detail and tactile surface variation. If the lower half is crowded, remove secondary motifs and restore paper. If the palette is muddy, neon, or candy-like, return to warm white, one high-key source color, and one restrained sunlit accent. Regenerate with one targeted correction when needed.
