Swiss Minimalist Shanghai Travel Poster — Line Art Prompt

Create a cinematic, fine-ink line art poster of Shanghai featuring detailed city sketches, landmarks, trams, and clean Swiss typography. Use it as a Arte Conceptual 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, style, parameters, and layout. 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.
