Dual Half Photo to Architectural Sketch Poster

A split-screen editorial design poster in a vertical 3:4 layout, strictly divided 1:1 vertically with top and bottom each occupying 50% height. Top half: Displays the reference photo with its original subject identity, posture, natural lighting, and authentic texture fully preserved, subtly color-graded with an art exhibition and high-end magazine finish. The environment extends naturally to fill the frame without distorting or stretching the subject. Bottom half: An architectural concept perspective sketch and minimalist hand-drawn design presentation derived from the top photo. Deconstructs the scene to isolate only the core subject, silhouette, architectural structure, and narrative gesture against a generous field of conscious negative space. Rendered in loose, refined architectural drafting line-work with visible construction lines, geometric reference marks, and subtle geometric cast shadows. Hand-colored selectively using 2 to 4 harmonious accent colors extracted from the top photo ([warm gray, pale sage green, soft wood tone, and muted sky blue-gray]), leaving the majority uncolored off-white. Typography & Details: Minimal editorial captions and tiny architectural annotations quietly set in the white space. Clean, sophisticated layout avoiding clutter, 3D CGI rendering, or heavy cartoon outlines.
