아이소메트릭 복셀 게임 에셋 시트 업그레이드

Based on the reference image, regenerate all isometric pixel art icons into richly detailed voxel-style illustrations. Preserve the exact layout, grid structure, [solid neutral] background color, and Japanese text labels. Upgrade each icon from simple low-poly shapes to detailed voxel models with ambient lighting, refined textures, and distinct features (such as windows and doors on buildings, equipment on characters, and textured surfaces on animals), while maintaining the original subject identities.
