Based on the uploaded 3D base image, generate a Sasaki-style multifunctional urban planning schematic diagram. Do not change the existing site content, building layout, road structure, green space, water bodies, spatial proportions, or the 45-degree isometric viewpoint.
Maintain the original 3D base content exactly, including the relative positions of buildings, roads, open spaces, landscape elements, and surrounding urban context. The result should remain the same scene, only upgraded into a refined urban planning visualization style.
Visual style: International landscape and urban planning competition board style, clean vector illustration, slightly technical but artistic, balanced information hierarchy, soft shadows, restrained hand-drawn texture, no photographic realism.
Building treatment: Buildings are simplified into white and light gray massing blocks with flat roofs. Use warm yellow and orange highlights on key functional rooftops to emphasize program identity and spatial importance. Surrounding urban background buildings are rendered in light beige with low detail.
Landscape treatment: Green spherical trees in vector style, scattered across open spaces and street edges. Add small-scale gray human silhouettes to indicate pedestrian scale and activity intensity.
Circulation system: Use thick red arrows to show pedestrian flow and direction. These arrows radiate from the site center toward surrounding areas, clearly indicating circulation distribution.
Functional zoning: Use yellow rectangular labels with bold black text to mark different functional zones. Add blue, green, orange, red, and purple area fills or transparent overlays to distinguish mixed-use areas, green infrastructure, public spaces, commercial corridors, and activity zones.
Color palette: Golden yellow, burning orange, deep red, sky blue, white, olive green, magenta. Keep the overall palette bright but professional, with strong graphic contrast.
Text and labels: All labels must be in English. Use yellow rectangular tags with bold black English text for functional zones. Use small clean English labels for streets, plazas, green spaces, waterfront edges, pedestrian corridors, activity nodes, and surrounding urban context.
Composition: One complete isometric planning schematic, no duplicate maps, no split panels. Keep the original 45-degree isometric perspective. High-density information but clear reading order. Soft building shadows, vector graphic style, professional urban planning presentation quality.
