UnsteadyTeddy: Thanks for the crit. A friend did a paintover for me, and said much the same thing as you about the mothership. The drone ship...I dunno, I did keep some of the styles similar (minus the blades obviously). I think it'll be a lot more obvious when I've got it textured.
Here's the final low poly (unless someone sees a glaring mistake...) :
Edit: That's 5,402 tris (mothership + 1 drone). I'd really love to blow 1600 more tris somewhere, but I've gotta get going on the uv and stuff. Clock is ticking!
