Prompt 👇
Premium minimalist flat-vector travel poster for [CITY_NAME], 3:4 vertical format.

Design an original, sophisticated travel poster that captures the authentic visual personality of [CITY_NAME]. The composition must feel purpose-built for this city rather than following a reusable template.

CITY IDENTITY

First interpret the unique visual character of [CITY_NAME] and build the scene around these five elements:

1. A recognizable landmark, architectural feature, or skyline element.
2. A distinctive local way of moving through the city.
3. One subtle everyday lifestyle moment.
4. A native plant, landscape, or environmental characteristic.
5. A composition and viewpoint that naturally belongs to the city.

The overall scene structure must change from city to city. Do not repeatedly use the same object positions or visual formula.

Possible compositions include:
harbor viewpoint, narrow historic lane, riverside garden, coastal path, elevated city overlook, lively market passage, tram avenue, ferry terminal, botanical setting, heritage square, beach promenade, cultural plaza, or skyline terrace.

Choose whichever composition best represents [CITY_NAME].

TYPOGRAPHY

Place “[CITY_NAME]” in the upper-left area with generous clean negative space.

Add one short, sophisticated English tagline inspired by the atmosphere of the city.

Typography should feel understated, editorial, spacious, and premium. Never allow text to dominate the artwork.

VISUAL HIERARCHY

Use one iconic landmark or architectural feature as the main focal point.

Support it with only 2–4 carefully selected local elements. Every added detail should strengthen the sense of place.

Avoid landmark collections or postcard-style collages. Keep the scene visually quiet and intentional.

PEOPLE

Include only 3–6 small-scale figures.

Give each person a believable activity connected to local life, such as:
walking through a historic lane, cycling, waiting for public transport, sketching architecture, boarding a ferry, reading outdoors, taking a quiet photograph, carrying beach equipment, browsing a market, or jogging beside the water.

Avoid crowds and avoid making any single person the main character. Figures should integrate naturally into the environment.

LOCAL CHARACTER

Use city-specific elements only when they genuinely fit [CITY_NAME]:

- local transportation
- architecture
- street furniture
- vegetation
- small signs or wayfinding
- local food references
- recreational activities
- pavement markings
- cultural details

Transport and signage should remain subtle. Instead of always using a large signboard, incorporate details naturally through a small transit marker, station clock, ferry information panel, bike symbol, painted road marking, beach flag, or understated metro icon.

ART DIRECTION

Japanese stationery-inspired aesthetic,
luxury sticker illustration,
premium commercial vector artwork,
modern editorial travel branding,
clean delicate outlines,
uniform line weight,
simple geometric forms,
flat-color illustration,
soft shapes,
balanced visual rhythm,
high-end minimalist postcard design.

COLOR SYSTEM

Build the atmosphere primarily with:
pale powder blue, soft sky blue, mist blue, and cool airy blues.

Balance these with:
warm ivory, cream, soft beige, muted sage, gray-green, and understated architectural neutrals.

Use dusty rose or muted blush only for tiny visual accents such as flowers, clothing details, small signs, awnings, or decorative objects.

Colors should remain soft, sophisticated, slightly desaturated, and cohesive.

MOOD

Fresh, airy, peaceful, refined, contemporary, elegant.

The final artwork should feel like a premium boutique travel postcard or luxury lifestyle brand illustration, with generous breathing room and a relaxed sense of place.

Every city must have its own visual identity.
