McDonald's x Starbucks Iced Dessert Poster — Sora 2 Prompt

Create a stunning co-branded poster of McDonald's Oreo McFlurry and Starbucks iced chocolate, with high-contrast 3D rendering, perfect for social media 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, format, aspect ratio, scene, branding, and headline. 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.
