Double-Sided Watercolor Coffee Picnic Flyer Mockup Prompt

Generate a warm, double-sided watercolor coffee picnic flyer with illustrations, vendor list, and schedule—perfect for event marketing. 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, left side front, and right side back. 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.
