EDIT: Just caught the part where he wanted it to be a carrier. Still, the model would work for either purpose, and seems to be closer to the Bullhead in size. This is based on the windows, not an actual modeled scale.
As far as the texturing, those vertical ridges on the upper corners of the primary body would look a lot better matte 'armor' gray as with the smaller underside sections. Otherwise the texturing is much improved over the previous model - good job!
