Hi there bobson,
first of all, welcome to Game-artist.net
I noticed that you used Chamfer quite alot on your model. They are a real pain in the but to unwrap/texture propperly imo, so if you aren't realy good at it i would definitly look into that, maybe make some changes here and there.
Atm you have 1200+ tris left. I'm absolutly positive that
you can do something with that.

Doesn't have to be uberoriginal or anything, if it's for practise, anything will do. It might be a good idea to take a look at other contestants, see what they are working on, and go from there
Cheers
