Vanas term 3 week 11 Gun Concept

I had the Idea to merge a 70's sci fi gun with an old pirate handgun. I really love the concept and learnt a lot from creating this mashup. In the future I plan to create more images that push my use of materials. I think that focusing on improving how I render materials will greatly help my future concepts.

Tips, or Critique?
I'd Love to hear it in a comment ;P
