The design looks inspired by the old Space 1999 Eagle transports, one of my favorite ships from years ago. This certainly has its own identity, though, and some of your detail work (particularly in the body) is terrific!
I like it. The colors are good and it holds a decent number of troops without compromising shape. It looks like the future equivalent of a Blackhawk helicopter; some missile racks or chain guns on the sides would be neat. Great job!
