Haven't downloaded it, but it looks good from the screenies.
A few suggestions though, if ya don't mind...
I would close up the two large empty spaces on either side if I were you. With just the two engines connected to the front like that, it doesn't look very aero-dynamic (that spelled right??) It would make a very nice hover-craft type vehicle if you went ahead and covered that, maybe even make the wings look like solar-panels or something.
Where does the driver sit? The whole front looks completely closed-in, replacing one of the panels with some sort of view-port would really make it look nice. But of course, it depends on what you're using it for, if it's supposed to be some sort of battle vehicle, then you'd best leave the front the way it it. But if it's for some joy-rider, you need it nice and sporty.
Very nice ship, lots of possibilites.
