AS Val

Hi guys! This is my first post here, so hi to all. I am now modelling stuff in Blender for quite some time, but I never was really good at what I was doing, I already tried to model quite a few guns and other stuff. But yesterday I began modelling an AS Val and I can just say I think it is my best model/render yet. I am quite happy with its general look and with the materials too. I dont consider it finished, though I also dont consider it WIP. UVs are not done (yet) as I am really bad with UVs. So I wanted to ask you guys what you think about it. It is a poly-model rendered in cycles with material-nodes (no textures used (no UVs)).
