### Full prompt
```text
An architectural observation poster with a [4:3 horizontal side-by-side composition], split cleanly down the center into two equal 50/50 halves with a straight, crisp, unfeathered dividing line without bleed or crossover.

Left half: Faithful representation of the reference photo, maintaining the exact architectural structure, perspective, materials, lighting, and ambient atmosphere. Enhanced with subtle, restrained high-end architectural editorial color grading, matching the texture of museum publications and design journals.

Right half: A modern Eastern ink-line and color architectural sketch reinterpreting the same scene on textured, warm off-white paper. Simplified visual hierarchy with bold, irregular black ink washes defining the rooflines, eaves, and primary masses, complemented by fine, slightly broken gray-black ink lines for structural outlines, columns, and perspective directions. Tiles, detailed carvings, and minor ornamentation are deliberately abstracted away. Trees and greenery are condensed into sparse dry-brush color blocks of [gray-green, moss green, sage green, olive green, or ochre]. Sky, air, and ground are represented by generous continuous negative space (40% to 60% of the surface). Water, if present, is rendered with sparse horizontal ink marks. The palette is restrained: black, warm gray, mineral tones, and a single focal accent of [vermilion] reflecting key figures, doors, or lanterns from the scene.
