Anime School Festival Flyer Prompt – Glossy Manga Girl Poster

Generate a detailed Japanese-style anime flyer featuring a gloomy schoolgirl mascot, vibrant purple accents, and full event details—ideal for promotional posters or social media. Use it as a Concept Art 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, setting, subject, layout, text treatment, and color palette. 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.
