Well...I don't want to be rude, but it doesn't look very well. First of all try to finish your model before texturing it. Second, get yourself _very_ good references (google,...). Third, do easy things to improve your skills and increase them step by step. If you haven't done them yet, do the Maya Tutorials which are enclosed with the software. Try to keep your mesh as clean as possible. In my opinion you shouldn't do an AK-47 if you're new to Maya. I hope I didn't discouraged you too much. I'm sure with some practise in the basic skills you will post another AK-47 in circa two months which is much better. And the one after, is even better and so on...

Keep it up.
