Brewster Buffalo

I’m working on yet another WWII plane (I like planes =D)
My previous one, was the Supermarine Spitfire
But now i’ve got a little more training with Blender (used it for about 3 weeks now, i guess) And i decided to make this one, Brewster Buffalo.

I would be glad if you would give some constructive critique on it. I try to stay lowpoly this time, because the spitfire became much too overloaded with vertices…!

Vertex Count: 1066 rendered (674 when editing - half the plane is mirrored)
Rendertime: 00:10:42
