城市旅行极简矢量海报设计指南

Premium minimalist flat-vector travel poster for [CITY_NAME], 3:4 vertical format. Create an original luxury travel poster that captures the true identity of [CITY_NAME]. Design a unique composition based on the city's character, not a repeated template. CITY ESSENCE: Include: • One iconic landmark, architectural feature, or skyline element as the main focal point. • A local transportation style or way of moving through the city. • One subtle everyday lifestyle moment. • Native plants, landscape, or environmental features. • A viewpoint that naturally represents the city (harbor, historic street, riverside, market, coastal path, garden, plaza, skyline terrace, etc.). Keep the scene quiet, elegant, and place-specific. Use only 2–4 supporting local details. Avoid postcard collages and unnecessary elements. TYPOGRAPHY: Place "[CITY_NAME]" in the upper-left with generous negative space. Add a short sophisticated English tagline inspired by the city. Typography should feel premium, editorial, minimal, and never dominate the artwork. PEOPLE: Include only 3–6 small figures naturally integrated into the environment. Show authentic local activities such as walking, cycling, commuting, sketching, reading, photographing, boating, shopping, or relaxing. No crowds and no main character. LOCAL DETAILS: Use authentic city elements only when relevant: • Transportation • Architecture • Street furniture • Vegetation • Small signs or wayfinding • Food or cultural details • Recreational activities Keep signs and transport subtle through details like transit markers, station clocks, ferry panels, bike symbols, road markings, or small icons. ART STYLE: Japanese stationery-inspired aesthetic, luxury sticker illustration, premium commercial vector art, modern editorial travel branding. Use clean outlines, uniform line weight, simple geometric forms, flat colors, soft shapes, balanced composition, and high-end minimalist postcard design. COLOR PALETTE: Primary: Pale powder blue, soft sky blue, mist blue, cool airy blues. Supporting: Warm ivory, cream, beige, muted sage, gray-green, architectural neutrals. Accent: Small touches of dusty rose or muted blush. MOOD: Fresh, airy, peaceful, refined, contemporary, elegant. QUALITY RULES: Every city must have a different camera angle, composition, landmark placement, foreground treatment, and visual identity. Do not simply replace the city name in an existing design. NEGATIVE PROMPT: No photorealism, realism, watercolor, painterly texture, gradients, heavy shadows, cinematic lighting, paper texture, excessive details, clutter, landmark collage, crowded streets, oversized characters, dominant hero figure, repetitive café scenes, fixed layouts, generic tourist poster style, copied compositions, or unnecessary decoration.
