I like this ship its a perfect idea for a fighter. its thin and full of holes thus making it hard to hit and judging by its shape I'd say its incredible agile too. even decently armed. but if and when you hit this thing I bet it will go poof. like tie fighters. still a very good concept.
some update I change small tube position, add forward engines for maneuvering (Small black apertures on a nose) Camo texture for test only Later I try create texture like in you sketch. I dont know how, my drawing skill are low
