Hidden Duck Hokkaido Travel Puzzle — Find the Secret Character

Create a vibrant, detailed miniature diorama illustration of a bustling Hokkaido festival, featuring a hidden yellow rubber duck for a fun find-the-object puzzle. Use it as a Концепт-арт 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, theme, main goal, composition, hidden object, characters, and visible text and signs. 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.
