Isometric Exploded Urban Asset Sheet | GPT Image 2プロンプトと調整メモ

A massive isometric exploded-view environment sheet showing a dense collection of modular retro urban buildings and room cutaways on a clean white background, rendered like a highly detailed game asset breakdown or architectural kitbash catalog. The image contains 20 main assembled structures or room modules, each separated into floating parts: 1 small gabled house with blue roof, 1 dark blue square building, 1 small rust-red house, 1 cylindrical weathered tower building, 1 white two-story house with blue roofs, 1 warm wood-paneled corner room, 1 compact study or office room, 1 bedroom, 1 dining room with balcony, 1 café or kitchen room, 1 narrow storefront room, 1 small lit alcove room, 1 large concrete stairwell block, 1 small tiled washroom, 1 medium concrete stair-and-landing block, 1 larger concrete stair platform block, 1 narrow concrete corridor or service block, 1 large empty concrete room, and 1 blue vending machine pair area. Surrounding all modules are hundreds of separated components arranged neatly in exploded fashion: roof panels, corrugated awnings, wall segments, doors, shutters, windows, stair flights, railings, balconies, signboards, pipes, antennas, utility poles, lamps, vents, meters, tanks, planters, flower boxes, benches, crates, air conditioners, cabinets, fences, street barriers, buckets, jars, utility boxes, and small street props. The style is painterly but precise, with cozy amber interior lighting contrasting against worn concrete, oxidized metal, chipped paint, rust-red and deep blue roofs, teal-green trim, and aged urban textures. Emphasize miniature diorama realism, isometric perspective, exploded assembly presentation, many floating parts evenly spaced around each structure, highly legible silhouette separation, soft studio shadowing, extremely intricate detail, concept-art polish, and the feeling of a comprehensive environment asset sheet for a side-street neighborhood in {argument name="city style" default="a nostalgic Japanese retro urban district"}. Include exactly 20 major modules, with the lower edge lined by many small props and potted plants, and keep the overall composition balanced across the full canvas. Use a crisp white background, no framing, no people, no vehicles except 1 bicycle, and no text labels.
