Minimal Flat-Vector City Travel Poster

Premium minimal flat-vector travel poster for [CITY_NAME], 3:4 vertical. Create a fresh, airy, elegant city travel poster that feels uniquely designed for [CITY_NAME], not reused from another city. IMPORTANT COMPOSITION RULE: Before drawing, identify the unique “city DNA” of [CITY_NAME]: 1. one primary landmark or skyline feature, 2. one local movement or transport cue, 3. one everyday lifestyle moment, 4. one native plant / local environmental detail, 5. one spatial composition that fits this city specifically. Do NOT reuse the same layout formula across cities. Avoid defaulting to: - a shop always on the right, - a signboard always on the left, - people always sitting at a café table, - the same foreground flower bed, - the same lamppost position, - the same waterfront promenade composition. Each city must have a different scene structure, chosen from its real atmosphere: harbour lookout, laneway street, riverside park, beach walk, hilltop viewpoint, market corner, tram street, ferry quay, botanical garden, old town street, coastal boardwalk, cultural square, or skyline overlook. Typography: Place “[CITY_NAME]” in the upper-left with generous typography-safe negative space. Add one short refined English caption that matches the city mood. Keep the typography elegant, minimal, and premium. Scene adaptation: Automatically adapt the scene to [CITY_NAME]. Use one iconic primary landmark as the main visual anchor. Add only 2–4 supporting local details that truly belong to the city. Do not create a landmark collage. Do not overfill the background. People: Use only 3–6 small figures. Each person should perform a city-specific everyday action: walking, sketching, cycling, waiting for a tram, boarding a ferry, carrying a surfboard, taking a quiet photo, reading in a park, jogging by the water, browsing a small market. Avoid crowd scenes. Avoid one dominant hero character. People should feel naturally placed within the city, not copied from previous posters. Local details: Use local transport, signage, street furniture, plants, food, architecture, and leisure details only when they fit the city. Transport signs must not always appear as a large vertical signboard. They may appear subtly as a tram stop marker, ferry route board, station clock, bike lane symbol, beach patrol flag, small metro icon, or painted pavement mark. Style: Japanese stationery aesthetic, luxury sticker illustration, premium commercial flat-vector travel poster, clean thin outlines, consistent line weight, flat colors only, soft minimal shapes, calm editorial composition. Palette: Use pale powder blue, soft sky blue, and mist blue as the atmospheric base. Use warm cream, soft beige, sage green, and muted gray-green for architecture and nature. Use dusty rose or blush pink only as tiny accents on flowers, signs, awnings, clothing, or small decorative details. Keep the palette refined, toned-down, and high-end. Mood: fresh, minimal, elegant, calm, refined, high-end travel postcard, quiet lifestyle branding, open space, breathing room, relaxed local rhythm. Negative prompt: No realism. No watercolor. No painterly effects. No photorealism. No heavy shading. No gradients. No paper texture. No dense background. No repeated café-on-right layout. No repeated signboard-on-left layout. No generic tourist poster collage. No crowded street. No oversized people. No dramatic lighting.
