Arkcon: Crap. I knew I ripped the name off from somewhere. Just didn't think it was here.
NullAshton: Thank you, this is the sort of comments I'm looking for. Not just 'Add more detail' but specifics as to what kind of detail. Much appreciated.
I originally did have engine glow in there, but some strange property of the texture I'm using caused it to 'bleed' out all over the place. I think I've found a way to fix it so I'm including an updated pic.
Oh, and Strategia, the Terrans are coming along fine, thanks. Although we suffered a serious setback last night when I was putting the finishing touches on the Heavy Carrier. Accidentally hit 'Randomize Size, Rotation & Position.' Twice, so I couldn't Undo. Never model drunk.
