way to go Bones, that looks awesome.
I have one idea for what make that ship look even better. On the drive section cylinder, the textures appear to dip slightly in the center of each polygon from certain angles like in pic 1. You can solve this by making the polygons all triangles instead of squares. I've attached a pic to show you what I mean.
On the other hand, I might be seeing things, so if I am, just disregard this.
