I agree with Luke, but overall it's a good build. Cool idea of adding the turret on the side as opposed to the back, like mine (which I will post soon, once I work out some glare issues!). This is also your first fully SNOT creation, correct?
I think the little cabin might look better offset to one side, or as a two seater going all the way across (a driver and a gunner, maybe?) Good work though, reasonably good photos that compliment it well as well.
