mosaic sphere 3d model

Create a clean production-ready 3D model based strictly on the reference image. Topology requirements: - Use clean, evenly distributed QUAD topology. - Prefer mostly 4-sided polygons. - Use uniform quad density across the entire model. - Keep polygon density moderate and optimized, not overly dense. - Create clean edge flow following the shape and curvature of the object. - Use proper supporting edge loops around sharp corners and important details. - Avoid extremely long, thin, stretched or irregular polygons. - Avoid random triangulation. - Avoid unnecessary vertices and unnecessary edge loops. - Avoid dense topology in flat areas. - Keep topology suitable for subdivision surface / smooth shading. Mesh integrity: - Make the model completely watertight and manifold. - No holes, gaps, cracks, open borders or disconnected surfaces. - No overlapping faces. - No duplicate vertices. - No internal floating geometry. - No non-manifold edges. - All connected parts should have clean topology
