Cool, my favorite part of your ship is the way the neck/bridge is elevated and the body is much bigger, definately looks like a troop transport/freighter. Interior is very roomy. Engine greebles are good. One thing though, I think it would look a bit more stream-lined if you removed one or two of the cannons on the dorsal side of the ship, and maybe replaced them with a more flat turret. Other than that, looks great. The cannons ("miniguns"?) on the left and right side of the body near the cockpit look great.
