Japanese Summer Festival Poster — Sora 2 Prompt

Generate a dramatic, print-ready festival poster with ink-brush calligraphy, fireworks, glowing lanterns, and customizable event details. Use it as a 컨셉 아트 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, format, overall style, color palette, main visual, background, and right date panel. 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.
