First real attempt at a character

Hey guys, I've been working for the past couple of months on this character for a uni project, and for someone who's neither strong in character modelling nor texturing, I think it didn't turn out too bad for a first real attempt. It's far from professional, but I'm learning at least. I attempted to gather inspiration from our group project and designed a Nazi soldier with three LOD's. The first (The one you see in these screenshots) is at 15,000 tris, the next was at 8,000 and the last was at a tiny 4,000. Here are the textures I designed: they include a diffuse, specular, normal, ambient occlusion map and a metal and roughness map as well. I used substance painter to design these, working with in built smart materials and using a combination of other materials to create my own smart materials as well.
