Make the Uvs take up less space. Textures didn't match reference closer. More wear inside the mortar. The alpha stamps were giving mixed messages about the age of the items. Presentation could be better. Make it look nicer and more of a scene.
Geometry was better. Be careful of pinching. Baked maps and UVs were missing.
The model wasn't high res. The model wasn't softened enough. Needed more fine tuning. The project parts needed to be put together. Take a better shot of asset.
