极简单色城市建筑线描海报生成指令

Generate a high-fidelity "Urban Line Atlas Poster." The design is based on the visual language of a monochrome urban line-drawing travel poster, featuring a visual framework consisting of a top title, middle streetscape depth, core landmarks, flanking buildings, foreground figures, and a bottom footer. [Theme City Details] - City Name: [Insert Name] - Main English Title: [e.g., TOKYO RHYTHM / SHIBUYA PULSE / URBAN LINE ATLAS] - Local Language Title: [Chinese or native name] - Country/Region: [Location] - Core Landmark: [Representative landmark] - Street Scene: [Specific neighborhood or atmosphere] - Mood Theme: [Commuter morning / Rainy street / Weekend afternoon / Sunset cycling / Twilight walk] - Color Palette: [Vermilion / Black-gray / Deep indigo / Dark green / Umber / Burgundy] - Aspect Ratio: [3:4 or 2:3 vertical] [Positioning] This is a hybrid of a travel memorial, urban visual atlas, architectural manuscript, and editorial cover. It should feel like a high-end urban archive rather than a generic tourist brochure—combining city recognition with authentic street-life vitality. [Composition] 1. Top Title Area: Bold and striking English titles, potentially including city codes, series numbers, coordinates, or subheadings. 2. Middle Streetscape: Deep perspective view. The angle can be centered, slightly tilted, or a high-angle view to ensure a unique composition. 3. Visual Anchor: Core landmarks should be recognizable in the mid or background, integrated naturally into the daily street scene. 4. High-Density Details: Flanking buildings should feature local facades, shops, road signs, traffic lights, subway entrances, and wires. 5. Human Elements: Include natural foreground elements like commuters, cyclists, tourists, coffee cups, or taxis to add a sense of life. 6. Footer: A standalone area designed like a city tag, travel receipt, or archive index. [Typography & Style] Text must be crisp and integrated into the design system. Use monochrome or minimal duotone line-drawing style on paper textures (cream/light gray). Lines should be precise and restrained, resembling architectural pen sketches or screen prints. [Innovation & Constraints] Please innovate in title placement, street perspective, and information modules. Avoid: Watercolors, thick painting, cartoon/chibi styles, cyberpunk, large color blocks, or cheap souvenir aesthetics. Generate a high-definition, clean-lined, collectible vertical urban poster.
