Vertical travel ink splatter collage poster

Create a vertical top-to-bottom comparison travel transformation poster. The upper half completely preserves the input real travel photo, maintaining the composition, quantity, perspective, and lighting of landforms, buildings, streets, lakes, plants, figures, or vehicles; use a narrow off-white divider in the middle. The lower half selects one to three most recognizable travel elements from the original image, disassembling them into dark brown ink lines, dry brushing, watercolor spot color blocks, torn paper edges, and controlled ink dots, recombining them into an urban ink-splatter travel collage with negative space. Colors are extracted from the original image and compressed into 4 to 6 spot colors, changing spatial organization through scale variations, paper overlaps, and negative space; signs are only used as local elements if they exist in the original image. Accurate short English theme titles and material fields can be added, do not fabricate place names or brands. Prohibit full-image filters, pure line art, unrelated landmarks, garbled text, logos, watermarks, and any badges.
