Urban Ink-Wash Travel Collage Comparison Poster

Create a vertical top-and-bottom comparison travel reinterpretation poster. The top half fully preserves the input real travel photo, keeping the composition, quantity, perspective, and lighting of the landforms, architecture, streets and alleys, lakes, plants, people, or vehicles; use a narrow off-white divider band in the middle. The bottom half selects one to three of the most recognizable travel elements from the original image, breaks them down into black-brown ink lines, dry brushing, watercolor spot-color blocks, torn-paper edges, and controlled ink dots, and recombines them into an urban ink-wash travel collage with open negative space. Colors are extracted from the original image and reduced to 4 to 6 spot colors; spatial organization is changed through scale shifts, paper-layer overlap, and negative space. Signboards appear only as local elements when they exist in the original image. You may add an accurate short English theme title and material fields without inventing place names or brands. Prohibited: full-image filters, pure line art, unrelated landmarks, garbled text, logos, watermarks, and any corner marks.

制作一张竖向上下对比旅行转绘海报。上半完整保留输入真实旅行照片，保持地貌、建筑、街巷、湖泊、植物、人物或交通工具的构图、数量、透视与光线；中间使用窄米白分隔带。下半从原图选取一至三个最有识别度的旅行元素，拆解为黑褐墨线、干刷、水彩专色色块、撕纸边缘和受控墨点，重组为有留白的都市泼墨旅行拼贴。色彩从原图提取并压缩为4至6种专色，通过尺度变化、纸片遮叠和留白改变空间组织；招牌只在原图存在时作为局部元素。可加入准确短英文主题标题和材料字段，不虚构地名或品牌。禁止整图滤镜、纯线稿、无关地标、文字乱码、logo、水印及任何角标。
