极简高级城市建筑线稿海报

With [City Name] as the theme, create a minimalist and high-end city architecture line art poster.

The visual uses deep cobalt blue pen line drawings / architectural sketches to represent the city's most recognizable streets, buildings, skylines, or natural landscapes, naturally integrating representative urban elements of [City Name], but do not pile up landmarks; maintain restraint, authenticity, and a sense of life.

Composition requirements:
The main subject of the image is concentrated in the bottom 1/3 area, with a small size, leaving a large amount of white space around it, especially at the top. The overall look is like a high-end architectural travel manuscript or an art-collection-grade city print.
A small number of life elements such as pedestrians, bicycles, trams, cars, streetlights, trees, and small shops can naturally appear in the scene to give the city a sense of breathing, but figures should not steal the spotlight.

Visual style:
Deep cobalt blue monochrome pen line drawings
Fine architectural hand-drawing and slight cross-hatching
Cream-white old paper / high-end textured paper background
Low contrast, low saturation
Minimalist, restrained, quiet
High-end editorial design feel
Architectural travel sketch feel
Large amount of negative space
Do not use heavy shadows
Do not use large areas of watercolor coloring
No 3D
No modern commercial illustration feel
No complex borders

Add a very small city name in the white space below the main subject:

【Chinese City Name】
【English City Name】

The text is centered, the font size is very small, use a thin, elegant, and scholarly font for Chinese, and a refined Serif font with appropriately increased letter spacing for English.
The text is only a finishing touch to the image and should not overshadow the city illustration subject.

Overall effect like:
Architectural travel manuscript × Classical city print × Minimalist art poster × High-end paper stationery

Ultra HD, exquisite details
