North American B-25

I started first drawing planes, actually, my first 3D Drawing was a plane, and i truly loved planes for a long time, now i just like WWII planes, especially bombers (B-25 was always my favourite )
So i tried to draw a plane again after a loong time, and i like the result.
Materials:
Pencils 4H-8B, and A3 Vellum paper (and blending stuf)
Time ~10 Hrs

Comments appreciated
