thats pretty OK you should give it a more streamlined look and for the tail gun use a lewis gun or somthing besides the minigun if you still have two miniguns mount them beside the cockpit. otherwise this is a fair ship.

I think you should make it a little less angular, and beef up its weapons systems.
The weapons are going to be upgraded, I was planning on doing that already. (Great minds think alike! ;)) I would also like to make it more rounded off/studless, but it is kind of hard to do that on this ship. I am still going to try though!
