Affiche Architecturale à Deux Volets

A standalone high-end design poster in a vertical 3:4 composition, cleanly divided horizontally into two equal halves (50/50 split) with a sharp, restrained dividing line where elements do not cross over. Output only the flat poster front without frames, mockups, or wall displays. Top Half (High-Fidelity Photo): Faithfully preserve and display the reference photo. Maintain the subject identity, number of subjects, structural details of buildings/landscape/figures, exact posture, spatial layout, authentic materials, natural lighting, and original perspective. Apply restrained editorial color grading, refined dynamic range, and subtle 35mm film grain fitting an architectural or travel art publication. Naturally extend the sky, water, or ground horizontally to fit the half-frame while respecting the original lighting and perspective. Do not alter or stylize the core subject. Bottom Half ([LAKESIDE TERRAIN] Style Study): Reconstruct the identical subject from the top half as a minimalist architectural and landscape prototype study rendered on warm ivory textured paper. Maintain the primary silhouette, volume blocks, spatial rhythm, key orientations, and signature color palette of the reference photo so the subject is instantly identifiable, while abstracting unnecessary surface details into clean conceptual design forms.
