城市墨迹旅行拼贴海报

Create a vertical before-and-after travel poster. The top half fully preserves the input real travel photo, maintaining the composition, quantity, perspective, and lighting of landforms, architecture, streets, lakes, plants, people, or transportation. The middle uses a narrow rice-white divider strip. The bottom half selects one to three most recognizable travel elements from the original image, deconstructing them into black-gray ink lines, dry brush, watercolor spot color blocks, torn paper edges, and controlled ink splatters, reassembled into an urban splashed-ink travel collage with negative space. Colors are extracted from the original image and compressed into 4 to 6 spot colors, reorganizing spatial composition through scale variation, paper cutout overlays, and negative space; signage appears only as a local element if present in the original image. You may add an accurate short English theme title and material fields, but do not fabricate place names or brands. Whole-image filters, pure line art, unrelated landmarks, text gibberish, logos, watermarks, and any corner marks are prohibited.
