Travel poster glazed mosaic comparison transformation

Create a vertical 3:4 top-bottom comparison travel transformation poster. The upper half completely preserves the input real travel photo, maintaining the composition, quantity, perspective, and real colors of 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 have a full-page mosaic filter, but instead, on an off-white or light gray paper surface, extract 3 to 5 most recognizable subjects from the original image, split and reorganize them into independent glazed mosaic relief components; each component consists of irregular glazed small tiles, with white grouting, real thickness, visible sides, soft shadows, and partial glazed reflections. Components are concentrated in the lower center or to one side, occupying about 55% to 70% of the lower half, with obvious white space preserved around them; reorganize the space through scale changes and component spacing, replicating the photo in non-proportional scales. Colors are refined from the original image into 4 to 6 limited colors. Add restrained and accurate English editorial titles and material fields in the white space, with fonts like museum or exhibition labels. Prohibit long paragraphs of text, gibberish, irrelevant landmarks, logos, watermarks, AI icons, original image icons, and uniform mosaic coverage of the entire image.
