High-Quality Voxel Game Asset Sheet

Using the provided reference image, regenerate all isometric pixel art icons with significantly higher quality and detail. Keep the exact same layout, grid structure, background color, and Japanese text labels unchanged. Upgrade each icon from simple low-poly blocks to richly detailed voxel-style illustrations with proper shading, textures, and distinct features (e.g., add windows/doors to buildings, weapons/shields to characters, fur details to animals). Maintain the same character designs and building types but make them look more polished and professional.
