Thanks again guys!
Well, i never got to start one the backside on the disc's; I saw some more pics and then I did some changes.

1) Cockpit done for the third time
2) Disc shape improved
3) The thing/shape Roman pointed out was way to big, it is now made thinner, and would barely be visible in a new comparison (never bothered to do it again, because I "found out" that the "lenses" in Maya contra Lucasfilm are different somehow, I'm not sure why). (I dont care to fiddle with the camera right now)
4) Landing wells done over
5) Scaled "escape-pods" down and made a new "casing".
Hmm. seemes like i "must" buy myself a new pizza

He, he luistlf, I love your models (especially the x-wing), I though that i would stay away from bigger models, but now I want to make an x-wing and then *sigh* a "rebel" Corvette.
