Anime Character Sheet Prompt — Sweet Potato Theme

Generate a warm, watercolor-style Japanese anime character reference poster featuring a high school girl with customizable name, hair, and full outfit details. Use it as a Konzeptkunst starting point for GPT Image 2: keep the visual structure and style constraints intact, then swap in your own subject, brand, or scene.

This prompt is organized as structured JSON with fields such as type, style, character, layout, text rendering, and mood. Keeping that hierarchy helps the model separate the subject, layout, interface elements, and detail constraints.

Start with small changes to subject, scene, camera, and color, then generate a few variations to compare composition and detail without turning the page copy into keyword stuffing.
