Affiche de voyage en collage à l'encre urbaine

Create a vertical before-and-after travel poster. The upper half fully preserves the input real travel photograph, maintaining the composition, quantity, perspective, and lighting of terrain, architecture, streets, lakes, plants, people, or vehicles; the middle uses a narrow rice-white divider strip. The lower half selects one to three most recognizable travel elements from the original image, breaking them down into black-gray ink lines, dry brush, watercolor spot color blocks, torn paper edges, and controlled ink dots, reorganized into an urban splashed-ink travel collage with white space. Colors are extracted from the original image and compressed into 4 to 6 spot colors, with spatial organization altered through scale changes, paper overlay, and white space; signage is only included as a local element if present in the original image. May include a short accurate English theme title and material field, without fabricating place names or brands. No full-image filters, pure line art, unrelated landmarks, text garble, logos, watermarks, or any corner marks.
