It's pretty good. First of all, it's not perfect size. It's still too small. Also, while some parts should only be four studs, other parts should be 6 studs. Yours looks a bit skinny. make the handle a bit thicker, and have the black grip slope up towards the handle at the back. To make it less flat looking, make some parts like the top-front gray part sloped on the sides. Nice work though. Check out my MA5B v3.5 Assault Rifle.
