I like it though it might have looked better if the griffon was facing the front of the ship not that back, but it's no biggy

Apart from that its a nice render! although may I ask a couple of things?
1) what is that "object" in the upper middle of the picture, it looks kinda like the object used to show a light is there in 3DX...
2) Have you ever thought of scalling down your Quantem Mechanics and watermark stuff? in some of your renders it's looked kinda out of place and makes the whole picture look a little less well done than if it wasnt there or was much smaller/slightly transparent... Just a little niggle of mine

Apart from that, nice one! Great looking ship!
