城市地标汇聚：仰视角度的海报系统

CITY: [TOKYO / NEW YORK / PARIS / DUBAI / YOUR CITY]
MAIN LANDMARK: [most iconic landmark]
OTHER LANDMARKS: [4–5 recognizable landmarks]
TYPE COLOR: [accent color]
FOREGROUND DETAIL: [cherry blossoms / taxi / leaves / palm leaves]
COUNTRY: [country name]

Create a 9:16 vertical city poster using iconic landmarks from the same city.

Treat each landmark as an independent architectural collage element rather than a realistic street scene. Place the landmarks around the edges of the frame using an extreme worm's-eye perspective, with their forms rising and converging toward the center of the sky.

Use the MAIN LANDMARK as the central vertical anchor. Keep it the most complete and recognizable structure in the composition.

Arrange the other landmarks from the upper-left, upper-right, lower-left and lower-right edges. Make them large near the frame edges and gradually narrower toward the center, creating a strong radial, upward-moving composition.

Do not follow real geographic positions. The goal is to reconstruct the visual identity of the city through its landmarks.

Behind the architecture, place the city name in huge ultra-tall condensed sans-serif typography. The letters should occupy around 45–60% of the image, partially hidden behind the landmarks while remaining clearly readable.

Keep the city-name typography clean, solid and sharp. No distressed texture, cracks or worn lettering.

Use a limited three-color system: warm off-white paper background, charcoal / grayscale architecture, one strong accent color for the city name.

Render the landmarks with realistic architectural photography, then add subtle vintage editorial print texture, fine grain, halftone and paper texture.

Add a small blurred foreground detail connected to the city, occupying only around 5–10% of the lower edge, to create depth and local atmosphere.

Core visual formula:
iconic landmarks + extreme low-angle perspective + radial convergence + giant city typography + limited colors + subtle foreground depth.
