That Whitestar is lookin' mighty cool Mav, but I do know where there is room for further details... the head. On either side of the head, there are mechanical sections visible, leading up to the nose cannon. The nose gun itself needs to be there, and while all the mechanical stuff can be quite easily done with textures, it could use an indentation for this area.
The only other thing I would possibly suggest, would be somewhat over-the-top and perhaps of little use. We saw during season 5, that the Whistars not only have a small bay at the back of the ship, but in fact some sliding bay doors. Lateral translation isn't completely supported under Bob's animation code, but it can be faked. I think it'd be cool to see, but its far from necessary. Besides, I've already added a bay path leading into the horizontal gap, between the rear fins.
