Minimalist City Travel Poster

A high-end minimalist flat vector travel poster created for [CITY_NAME], 3:4 vertical scale.
Create a transparent urban scene, with a large negative space in the upper left corner suitable for layout.
Add [CITY_NAME] and a brief, elegant English description that matches the city's atmosphere.
Automatically adjust background based on city:
An iconic main landmark, local architecture, café culture, traffic signs, streetlights, flowers, trees, fine decorative details, and peaceful moments of daily life.
Use only 3–6 people to interact naturally with the city:
Chat, walk, jog, sketch, or take photos in a café.
Avoid crowding and avoid having a single main character.

Blush pink, dry rose, sage green, warm cream, soft beige, soft gray-green.
Atmosphere:
Minimalist, elegant, calm, refined, and a high-end travel postcard and lifestyle brand.
