Enhance this axonometric architectural model without altering its geometry, proportions, or layout. Smooth all edges and refine the surfaces. Apply realistic concrete material to all structural elements and realistic metallic mesh material to the lateral panels. Maintain the exploded axonometric separation of systems exactly as in the reference. Improve overall render quality and clarity. Keep clean lighting and a pure white background. Do not change the design, add elements, or modify the composition — only enhance it with proper materials and smoother edges.
