거대한 오커 기하학 포스터 변환

Convert the input city travel photos into a vertical 3:4 before-and-after poster. The upper 50% retains the main memorial architecture, towers, facades, plazas, and sky from the real photos; the lower 50% is translated into "MONUMENTAL OCHRE GEOMETRY | Ocher Gold Monumental Geometry Architecture Poster Style". In the lower half, reorganize the single main building from the photo using dark gray architectural linework, pen hatching, woodcut-style shading, and fine halftone dots; behind it, place one large-scale ocher-yellow circle, semicircle, or curved geometric color field, supplemented by no more than two cream white/charcoal black geometric shapes. Compress the plaza into a few flat color planes, retaining a few figures from the original photo for scale reference. Warm gray paper, paper fiber, and old poster wear; the title uses only "MONUMENT". The lower half must not be pure geometric abstraction or a whole-image filter; the center line must be clear. Avoid ukiyo-e, 3D, logos, watermarks, fake Chinese, garbled text, or original/AI image corner marks.
