City Travel Sticker-Style Flat Poster

Premium minimal flat-vector travel poster for [CITY_NAME], 3:4 vertical.

Create an airy city scene with large typography-safe negative space in the upper-left.
Add [CITY_NAME] and one short elegant English caption matching the city mood.

Automatically adapt the background to the city:
one iconic primary landmark, local architecture, café culture, transport sign,
street lamp, flowers, trees, small decorative details, and calm daily-life moments.

Use 3–6 people only, naturally interacting with the city:
talking at a café, walking, jogging, sketching, or taking photos.
Avoid crowds and avoid a single hero character.

Style:
Japanese stationery aesthetic, luxury sticker illustration,
premium commercial flat-vector poster,
clean thin outlines, consistent line weight,
flat colors only, no shading, no gradients, no texture.

Palette:
blush pink, dusty rose, sage green, warm cream, soft beige, muted gray-green.

Mood:
minimal, elegant, calm, refined, high-end travel postcard and lifestyle branding.

No realism, no watercolor, no painterly effects, no photorealism, no dense background.
