What Masao said... Plus I'd like to add try to break up the texturing a bit or create custom textures for each object. It destroys the illusion a little if the whole thing is uniformly textured the same way.
BTW, I use animation master from
www.hash.com which you can get for $199 to $299 depending on if you can find it on sale somewhere like
www.dvdirect.com. I think my stuff comes out all right for such an inexpensive package, plus it's really good for TOS stuff because it uses Bezier patches instead of polygons.
