幾何塊面拼出的日式旅行海報

A mid-century Japanese travel-poster homage for [CITY, COUNTRY], locked to a 4:5 vertical frame. Lean on flat-vector craft: bold geometric blocks, an editorial sense of composition, buildings reduced to their essentials, storytelling carried by shape rather than detail. Scan [CITY, COUNTRY] for its single most recognizable landmark plus the streets, transit, landscape and cultural notes that go with it, then fuse them into one original scene. Layer the depth deliberately — foreground, middle ground, background — around a single dominant focal point. Perspective should feel decisive: geometric streets, architectural silhouettes, pared-down greenery, an atmospheric sky, and only a handful of human figures just to set the scale. Palette stays tight and retro: deep navy, indigo, teal, turquoise, warm cream, mustard, ochre, coral, vermillion, forest green. Push color blocking hard and light the scene graphically — shadows and highlights built from geometry, never a realistic lighting rig or a smooth gradient. Finish the surface like it actually came off a press: faint vintage paper grain, screen-print texture, a little ink drift, restrained halftone. The landmark and cultural cues must stay recognizable even after the simplification — clean shapes, crisp edges, a composition that balances, a perspective under control, legible at a glance from across the room. Steer clear of: photorealism, 3D render, glossy finish, over-detailing, complex gradients, neon, visual clutter, heavy grunge, over-inked outlines, bokeh, lens flare, warped architecture, skewed perspective, stray objects, unreadable type, or any generic AI-art look. Target: a museum-shop-worthy Japanese tourism poster — bold, elegant, atmospheric, distinctly tied to its culture, built as one coherent, professional piece. Hold the line on the 4:5 vertical frame. Make the artwork entirely original and specific to [CITY, COUNTRY] — never a copy of an existing piece.

一張致敬中世紀日式旅行海報風格的作品，主題是[CITY, COUNTRY]（城市，國家），鎖定4:5豎版畫幅。 靠扁平向量功底說話：大膽的幾何色塊，編輯式的構圖感，建築被簡化到只剩骨架，敘事靠形狀而不是細節堆砌。先鎖定[CITY, COUNTRY]最具辨識度的那一個地標，再配上與它相關的街道、交通、風景和文化線索，融進同一個原創場景裡。 刻意分出景深層次——前景、中景、背景——圍繞一個主導視覺焦點展開。透視要夠果斷：幾何化的街道，建築剪影，簡化到極致的植被，有氛圍的天空，再加幾個人物形象只是為了交代尺度。 配色收得緊、帶復古味：深海軍藍、靛青、藍綠、松石綠、暖奶油色、芥末黃、赭色、珊瑚紅、硃紅、森林綠。色塊對比拉滿，用圖形化的方式打光——陰影和高光都由幾何形狀本身決定，不要真實布光，也不要柔和漸變。 表面質感要做得像真的印出來的：淡淡的復古紙張顆粒，絲網印刷的質地，一點墨色漂移，剋制的半調網點。 地標和文化元素簡化之後依然要認得出來——乾淨的形狀，銳利的邊緣，均衡的構圖，可控的透視，隔著房間一眼就能看懂。 避開：照片寫實、3D渲染、光面質感、過度刻畫細節、複雜漸變、霓虹色、畫面雜亂、重磨損感、描邊過重、散景、鏡頭光斑、建築變形、透視歪斜、無關物件、看不清的文字，以及任何一眼就能認出的AI生圖味。 目標：一張配得上放進博物館商店賣的日本旅遊海報——大膽、優雅、有氛圍、文化屬性鮮明，整體做成一件專業作品。 4:5豎版畫幅不能讓步。為[CITY, COUNTRY]做一張完全原創的作品——不要照搬任何現成畫作。
