手绘水彩旅行海报：城市墨线几何天际

Create a premium vertical travel-poster illustration for [CITY], [COUNTRY], designed for maximum Instagram engagement. Blend expressive hand-drawn ink/marker linework, rich watercolor washes, and selective low-poly/faceted geometry. Keep major landmarks highly detailed and recognizable, while using geometric forms for the sky, water, foliage, distant buildings, and atmospheric depth.

Create a cinematic, richly layered yet clean city scene featuring [3–6 ICONIC LANDMARKS], local architecture, transportation, people, streets or waterfronts, vegetation, and culturally distinctive details. Use a vibrant destination-specific color palette, dramatic lighting, crisp silhouettes, strong foreground/midground/background depth, and tactile visual texture. Maintain a clear focal hierarchy and avoid visual clutter.

At the top, feature a huge, bold, colorful hand-rendered "[CITY]" title, followed by the short emotional tagline "[TAGLINE]". Near the bottom, add subtle destination branding: "[CITY]
  • [COUNTRY]" and "[SHORT EMOTIONAL PHRASE]". Typography should be stylish, highly legible, integrated naturally into the artwork, and balanced with generous negative space. Add only a few tasteful decorative accents such as birds, hearts, cultural symbols, or brush marks.

Format: 4:5 Instagram portrait, premium poster quality, instantly recognizable at thumbnail size, strong central focal point, balanced composition, rich detail without clutter. Prioritize visual novelty, destination recognition, emotional appeal, shareability, and a strong "save this for later" travel feeling.

Avoid: generic stock-photo aesthetics, photorealism, infographic/card layouts, excessive text, generic landmarks, logos, watermarks, and cluttered composition.
