The quality hits different in GPT Image 2.5 Prompt: Create a premium retro-modern Japanese geometric travel poster for [CITY, COUNTRY] in a STRICT 4:5 VERTICAL ASPECT RATIO. Use a sophisticated flat-vector, mid-century Japanese travel-poster aesthetic with bold geometric shapes, elegant editorial composition, simplified architecture, and strong visual storytelling. Automatically identify and feature the most iconic landmark, architecture, streets, transportation, landscape, cultural elements, and atmosphere of [CITY, COUNTRY] in one cohesive original scene. Create clear foreground, middle ground, and background depth with one dominant focal point, strong perspective, geometric streets, architectural silhouettes, simplified vegetation, atmospheric sky, and minimal human figures for scale. Use a limited retro palette of deep navy, indigo, teal, turquoise, warm cream, mustard, ochre, coral, vermillion, and forest green, with strong color blocking and dramatic graphic lighting. Use geometric shadows and highlights rather than realistic lighting or complex gradients. Add subtle vintage paper grain, screen-print texture, slight ink variation, and restrained halftone detail for an authentic printed-poster finish. Keep landmarks and cultural elements recognizable yet artistically simplified, with clean shapes, crisp edges, balanced composition, controlled perspective, and strong readability from a distance. Avoid: photorealism, 3D rendering, glossy surfaces, excessive detail, complex gradients, neon colors, clutter, heavy grunge, excessive outlines, bokeh, lens flare, distorted architecture, warped perspective, random objects, illegible text, and generic AI-art appearance. FINAL LOOK: Museum-quality collectible Japanese tourism poster—bold, elegant, atmospheric, culturally distinctive, cohesive, and professionally designed. IMPORTANT: Strictly maintain the 4:5 vertical composition. Create a completely original artwork specifically adapted to [CITY, COUNTRY]. Do not copy any existing artwork.
