Mixue Bingcheng x Starbucks Matcha Poster — Sora 2 Prompt

Generate a bright co-branded matcha drink poster featuring Mixue Bingcheng and Starbucks, with mascot, pricing, and retail design for summer ads. Use it as a コンセプトアート 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, branding, scene, layout, main products, and mascot. 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.
