The ship looks really nice now, but I still think it's lacking something. Maybe add some details to the wings (maybe extend them somehow and connect them to the main body of the ship further up?) and the sides of the forward part (unless that's the place for the guns) as they really look empty at the moment.
on second glance, the fins on the insides of the rails are interfering with the escape pod bays on the underside of the ship, guess I gotta remove them...
