Conversão de Pôster de Geometria Ocre Monumental

Transform the input city travel photos into a vertical 3:4 before-and-after illustrated poster. The top ~50% retains the main commemorative architecture, towers, facades, plazas, and sky from the real photo; the bottom ~50% is translated into "MONUMENTAL OCHRE GEOMETRY | 赭金纪念碑几何建筑海报风". In the bottom half, reorganize the single main building from the photo using dark gray architectural line drawing, pen hatching, woodcut-style shading, and fine dot screens; behind it, add a large-scale ochre-yellow circle, semicircle, or arc-shaped geometric color field, supplemented by no more than two cream-white/charcoal-black geometric shapes. Compress the plaza into a few flat color surfaces, retaining a few people from the original photo as scale references. Warm gray paper, paper fiber, and old poster wear; the title uses only "MONUMENT". The bottom half cannot be pure geometric abstraction or a whole-image filter; the midline must be clear; no ukiyo-e, 3D, logo, watermark, fake Chinese, garbled text, or original/AI image corner marks.
