Affiche Avant/Après de Diorama de Voyage en Briques

Transform any input travel photo into a standalone 3:4 vertical before-and-after comparison illustrated poster. The upper half fully preserves the original real travel photo, maintaining the location, architecture or natural landscape, composition, perspective, number of subjects, character poses, and relationship with the environment, with only light publication-grade color grading; a thin, clean white horizontal divider line sits in the middle. The lower half rebuilds the same scene as a real, photographable solid plastic brick miniature diorama model, using plastic bricks with individual studs, connection seams, and clear part edges, accurately preserving the main outlines, spatial hierarchy, and iconic elements of the original photo, while actively reducing the scale of subjects, simplifying the background, and reorganizing everything into a complete small travel scene model. The model must have the real structure of solid bricks: studs, seam lines, wall thickness, steps, baseplate, roof or terrain variation, transparent windows, miniature vegetation, and contact shadows. The model scale is relatively compact, with tabletop negative space left around it, using a slight tilt-shift macro photography depth of field. Brick colors are extracted from the original photo and are not fixed to island blue; architecture, streets, bridges, mountain villages, cities, natural landforms, or character scenes all apply. The lower half may only use elements truly visible in the original photo, without adding waves, palm trees, boats, landmarks, or people out of thin air. A clear "real photo - solid brick model" top-to-bottom comparison must be formed. Do not make it pixel art, voxel rendering, mosaic, block filter, low-poly CGI, smooth clay, paper craft, felt, oil painting, watercolor, flat illustration, or ordinary cartoon; do not apply a brick texture over the entire photo. No text, titles, subtitles, original/AI image corner labels, logos, watermarks, decorative borders, and no stitching of multiple photos.
