上海拼貼海報，有著寫實天際線與地標、建築、城市氛圍的水彩插畫

提示詞

Create a strict 3:4 vertical travel-memory collage poster based entirely on the written description of [LOCATION].

Divide the poster into two horizontal halves.

TOP HALF - ~50%: Create a premium travel photograph-style scene of [LOCATION], showing its most recognizable landmark, environment, atmosphere, architecture, and local character. Make the scene realistic, cinematic, naturally composed, and geographically recognizable.

BOTTOM HALF — ~50%: Create a handmade travel-memory illustration of the same location on warm off-white uncoated paper, with a continuous 4–5% blank margin. On the left 66–68%, place one large, near-square, borderless illustration featuring the main recognizable landmark or subject. Below it, leave a pale paper strip and center exactly 3 short English keywords in the format “Keyword1·Keyword2·Keyword3”.

On the right 30–32%, arrange exactly 6 separate travel-journal stickers inspired by authentic visual elements of [LOCATION]: landmark detail, person/animal variation, environment, architecture/structure, functional object, and atmosphere/scale element. Give each sticker a slightly irregular warm-white hand-cut border and subtle paper shadow.

Use a unified matte gouache + cut-paper + risograph/screen-print aesthetic with coarse grain, slightly rough edges, subtle print-registration shifts, generous negative space, and only 5–8 low-saturation colors. Reduce the scene into large clean shapes, calm color fields, grouped vegetation, flat architectural forms, and simple faceless silhouettes.

Keep the most recognizable landmark of [LOCATION] as the Identification Anchor, preserving its distinctive silhouette, proportions, and signature colors. Fully redraw everything in the same flat, grainy medium.

Include only the 3 keywords and, if essential, one landmark word. No other readable text, titles, dates, captions, addresses, prices, watermarks, or signatures.

Avoid gradients, 3D effects, anime, polished vector art, clip-art, watercolor bloom, wet-marker texture, photographic rendering in the illustration half, or unrelated elements.

The final design should feel quiet, restrained, vintage, handmade, tactile, and premium - a travel postcard combined with a collectible sticker sheet.
