Mosaikfliesen-Relief-Reiseplakat

Create a vertical 3:4 top-bottom comparison travel illustration poster. The upper half fully retains the input real travel photo, preserving the composition, quantity, perspective, and true colors of the gardens, pavilions, towers, river alleys, bridges, water surfaces, buildings, and plants; use a thin white dividing line in the middle. The lower half should not be fully covered with a mosaic filter; instead, on a cream-white or light gray paper background, extract 3 to 5 of the most recognizable subjects from the original image, split and reassemble them into independent stained-glass mosaic relief components; each component consists of irregular glass tile pieces, with white grout lines, real thickness, visible sides, soft shadows, and localized glass reflections. The components are concentrated in the lower center or on one side, occupying about 55% to 70% of the lower half, with clear white space around them; reorganize the space through scale variation and component spacing, not proportionally replicating the photo. The colors are distilled from the original image into 4 to 6 limited colors. In the white space, add restrained and accurate English editorial titles and material fields, with typography resembling museum or exhibition labels. Prohibit long paragraphs of text, garbled characters, irrelevant landmarks, logos, watermarks, AI corner marks, original image corner marks, and uniform mosaic coverage over the entire image.
