简约风广场公园场景人物行走插画素材

Convert this image into a flat vector architectural illustration style, maintaining the exact same bird's-eye perspective, composition, proportions and camera angle. Use pastel color palette: pale yellow, light purple, light green, and cool gray. Replace complex realistic textures (like wood, water, concrete) with simple, clean geometric flat color blocks. No realistic shading, highlights, or cast shadows. Replace people with minimalist flat line-art silhouettes. Replace trees with semi-transparent flat gray vector shapes. Flatten the ground into solid light gray and white tones. Overall aesthetic: architectural diagram, isometric vector art, abstract geometric origami style.
