I've started on a new model, experimenting with a new technique for modeling it. I started with a rounded box, and then replaced that with a number of smaller rounded boxes. Then I went in and added better approximations of the final shape. Basically, it was to be a way to model without doing any 2d concept art in advance.
Obviously, I haven't finished the 'better approximations' step. Once I finish with this step, I'll probably go back and tweak/redo some parts.
I'm thinking about putting a fighterbay in that exposed region on the underside.
