So I've finished it. My ability with realistic textures has certainly improved but I still have a lot to work on. At the end of the model I see many things I would have done differently but then, hey that's learning right?
Anyway here's the final piece. I'll put up some wire-frames later.
I aimed for around 6,000 tris and and after optimising from around 8,000 I finished with 6,338, I give myself a 10% deviation on poly limits so I hit my mark.
If anyone see's anything I should fix please say so. For now I need a break till my next project.
