Hey, thanks for the comments!
@snader: My concept art is on paper and as I am no artist, it isn't really impressive to look at. You are right, I should definitely add some details on the starbase. (which is indeed a refueling station) And probably on the smaller crafts, too.
@questseeker: Yeah, more details on the Interceptor!
@willows: Well, what is the "typical" terrestrial battlecruiser? Is it edgy? Is it round? It is hard to say, because there are only fictional battlecruisers to look at. In Star Wars, these star destroyers are edgy, where in Perry Rhodan the terrestrial battleships are all spherical, and in Star Trek it is kind of a mixture, isn't it? But finally, I have to agree with you. The old version really looks like a bigger version of the transport ship.
@TrevoriuS: As far as I know the iPhone specs are like this: 480x320, 24 MB texture memory, textures up to 1024x1024, over 2000 polys with "very good" speed. So yes, 600 polygons for a craft would be indeed way to much. Actually, I still want to keep them prerendered, so the polygons are not the problem, but the 24 MB texture memory. "lowpoly" is with me as a fallback option - let's see how it will develop. By the way, the required number of rotation angles for a smooth rotation depends also on the rotation speed. So 32 angles may only be enough for small, fast rotating objects.

The fleet of the Fanatics Empire / the new Battlecruiser (reduced to 400 polys) better?

A first attempt on texturing. I only wrapped the texture on the sphere of the supplyship, so far. Well, looks a bit boring. Any hints?
