Transform an input travel photo of world architecture into a vertical upper-lower comparison art image. The upper part completely preserves the original real photo, maintaining the architectural identity, main structure, shooting perspective, composition proportions, lighting, and environmental characteristics, without any illustration processing; the middle is naturally separated by a clean white horizontal line. The lower part reconstructs the same building from the photo as an exquisite, realistic, and clearly volumed miniature 3D architectural model, accurately preserving its iconic outline, floor relationships, roof or dome, columns, doors and windows, arches, pedestal, and material characteristics, presenting clear thickness, concave and convex structures, contact shadows, and macro model photography depth of field. The model scale is relatively compact, displayed centered within a large area of off-white paper blank space. Add thick impasto oil paint with stacked textures only to the model base, ground, vegetation, water surface, clouds, and environmental shadows, making the impasto the environmental material supporting the three-dimensional model, and it must not cover or replace the main body of the building. The overall presentation has a quiet, restrained, and high-end contemporary gallery display feel. Do not make the building into a flat oil painting, ordinary illustration, or cartoon; do not add people, animals, vehicles, text, titles, subtitles, original or AI image corner marks, logos, watermarks, or decorative borders.
