Ooh lovely... the lighting is really making it quite dramatic. In the top shot, it's very much a Starship.
I, too, quite like the top image. I'm presently trying to think of extra bits of detailing (but not too much) to create a bit more visual texture. I'm also going with panels and sections of the hull done in slightly different tones. Finally I'll move on to the signage.
I still think of this as the Valiant
even though I haven't finalized on a name yet.
