Urban Juice Ad Prompt — Bold Lifestyle Poster Generator

Generate a photorealistic vertical beverage ad with bold typography, product focus, and a vibrant urban setting for premium juice branding. 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, format, brand, headline, scene, main subject, and hero product. 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.
