Cartel de viaje con relieve de mosaico

Create a vertical 3:4 top-bottom comparison travel poster. The upper half fully preserves the input real travel photo, maintaining the composition, quantity, perspective, and true colors of the gardens, pavilions, towers, river alleys, bridges, water surfaces, buildings, and plants. Use a thin white divider 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, then split and reassemble them into independent stained-glass mosaic relief components. Each component is made 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 center or on one side of the lower half, occupying about 55% to 70% of that section, with clear white space around them. Reorganize the space through scale variation and component spacing, reproducing the photo without equal proportions. 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 across the entire image.
