Wow, great machine! And I love this POV, really drags you into the scene. Yes, some weathering would make it more used. Some people? To make it more moving (not literally) you could think about some blur in the propellors, but you'd have to replace them with a blurred image map and a glass surface. Could be added as alternative to the ship, just add a zero opacity default shader to rule out either (prop or blur).
