โปสเตอร์คอลลาจโมเสกเรขาคณิตสองชั้น

An independent high-end design poster based on the reference photo, formatted in a 3:4 vertical composition with a dual-layer split layout. The top half features the realistic photography of the reference photo, retaining the subject's identity, structure, posture, authentic texture, and natural lighting with subtle art-magazine color grading. The bottom half is an artistic geometric deconstruction of the original subject's core silhouettes and narrative relationships, rendered in [geometric composition + intelligent mosaic reorganization]. The bottom half compresses the scene into clean geometric facets, modular rectangular units, fine line frames, and layered structural grids with stepped edges, creating a rational architectural diagram and modern mosaic aesthetic. The background of the bottom half is ultra-light near-white with generous negative space and breathable composition. The color palette follows a [warm, bright, and slightly naive artist's palette], utilizing flat cream yellow, apricot, coral pink, sky blue, and mint green with restrained visual accent anchors. Includes quiet, minimal, thin typographic design elements seamlessly aligned with the grid.
