What it does
This prompt directs the creation of a square, ultra‑high‑resolution, photorealistic underwater album cover by transforming a provided portrait into a cinematic scene where the same recognizable subject—kept fully identity-accurate—floats horizontally in loose dark streetwear beneath a pale wooden door near the water’s surface. It specifies precise pose, framing, lens and exposure characteristics, and a clean cobalt-to-navy environment with volumetric sunlight, subtle bubbles, and dreamy door reflections, while enforcing strict realism constraints to avoid cutout edges, graphic artifacts, or extraneous elements, resulting in a moody, editorial, Billie Eilish–inspired cover image ready for release use.

Inputs
textInputs
Pass each text input using --input <key>=<value> flags.
| Variable key | Required? | Description | Defaults |
|---|---|---|---|
pose |
Optional | Define how the subject’s body should be positioned in the underwater scene | horizontal floating with arms relaxed, head tilted upward, knees slightly bent |
wardrobe |
Optional | Specify how the subject’s clothing should be transformed to match the Billie Eilish vibe | loose, oversized, dark-colored outfit |
imageInputs
This prompt requires exactly 1 image. You must pass exactly 1 image flag (no more, no fewer), in the order matching the descriptions below.
| Index | Required | Description | Allowed CLI flags |
|---|---|---|---|
| 1 | Yes | Upload a clear portrait photo of you (frontal or three-quarter view) | --image-input-url <url> or --image-input-path <path> |
Models and options
This skill's modality is: image.
To discover which model values you can use (and which options keys/values are valid for each model), run:
betterprompt resources --models-only --json
Then filter the returned JSON array to entries where modality is "image".
How to run
Step 1: Collect inputs
First, run betterprompt resources --models-only --json and filter to modality: "image" to discover valid models and available options:
betterprompt resources --models-only --json
Use only the models and option values that appear in the filtered results.
Then collect all inputs from the human:
- Optional text inputs (use defaults if not provided by the human):
pose(default:horizontal floating with arms relaxed, head tilted upward, knees slightly bent)wardrobe(default:loose, oversized, dark-colored outfit)
- Required images:
- Exactly 1 images: image 1 (Upload a clear portrait photo of you (frontal or three-quarter view)). Images must be provided in this order.
- Optional: model and options.
- Present the human with the default model
gemini-2.5-flash-image-previewand its available options. Look upgemini-2.5-flash-image-previewin thebetterprompt resourcesoutput (filtered to modality"image") and show itsavailableOptionsas:key: val1, val2 (default), val3 | key2: .... Mark a value(default)if it matches these defaults:{}. - If the human does not specify, defaults are used: model
gemini-2.5-flash-image-preview, options{}. Other models from the resources call are also available.
- Present the human with the default model
If the required images are missing, ask the human for what's missing. Do not assume or fabricate values. Tell the human: "Please provide images in this order: image 1 (Upload a clear portrait photo of you (frontal or three-quarter view))".
Step 2: Run via BetterPrompt CLI
Use the frontmatter's name as the positional argument (for this skill, use billie-eilish-subaquatic-album-cover).
Command form:
betterprompt generate billie-eilish-subaquatic-album-cover \
[--input <key>=<value>] \
[--image-input-url <url>] \
[--image-input-path <path>] \
[--model <model>] \
[--options <options JSON>] \
[--json]
Notes:
- Pass each text input as a separate
--input <key>=<value>flag. - Pass each image using
--image-input-urlor--image-input-path, in the order matching the imageInputs descriptions (image 1 first, then image 2, etc.). - If the human does not mention a model, omit
--modeland BetterPrompt will use the default model:gemini-2.5-flash-image-preview. - If the human does not mention options, omit
--optionsand BetterPrompt will use the default options:{}. - If the run times out, the response will include a
runIdyou can use to fetch the result later.
Example (using defaults shown above):
betterprompt generate billie-eilish-subaquatic-album-cover \
--input 'pose=horizontal floating with arms relaxed, head tilted upward, knees slightly bent' \
--input 'wardrobe= loose, oversized, dark-colored outfit' \
--image-input-url https://example.com/image1.png \
--model gemini-2.5-flash-image-preview \
--options '{}'
