Yep... It would be a waste of polys to model anything like that WC2 thingmajig there... it has a pretty tricky shape, and serves no practical purpose. It would also be a waste of a pretty good turret location.As for the communications array and the textures... I don't know why they're different. In the case of the communications array, Eder probably simply didn't want to waste polys on such stuff.
I'm not even sure. I seem to remember having seen the front part as gray and the keel as something darker than the other green parts of the ship (whether it was still green or not, I don't remember)... that model is pretty old, and I didn't check the original one to make it.And textures... most likely, he just felt like doing them that way .
As for the red lights, they're not there because painting lights on a texture usually makes for a very ugly effect, as can be seen on some ships' engines. Therefore I tried to avoid that effect as much as possible (the red lights on the frontal part of the Gilgamesh's engines, for example, don't look as bad since it's a mostly plain black background).
