Conversión de Póster de Geometría Ocre Monumental

Convert the input city travel photo into a vertical 3:4 before-and-after poster. The top half (about 50%) keeps the main commemorative architecture, towers, facades, plaza, and sky from the real photo; the bottom half (about 50%) is translated into "MONUMENTAL OCHRE GEOMETRY | Ochre-Gold Monumental Geometry Architecture Poster Style". In the bottom half, reorganize the single main building from the photo using dark gray architectural linework, pen hatching, woodcut-style shading, and fine halftone dots; place a large-scale ochre-yellow circle, semicircle, or arc-shaped geometric color field behind it, with no more than two cream-white/charcoal-black geometric shapes as accents. Compress the plaza into a few flat color planes, keeping a few original figures from the photo for scale reference. Warm gray paper, paper fiber, and old-poster wear; title only "MONUMENT". The bottom half must not be pure geometric abstraction or a whole-image filter; the center line must be clear. No ukiyo-e, 3D, logos, watermarks, fake Chinese, garbled text, or original/AI image corner marks.
