Good luck dude, I read the post about photoshop expiring, ouch. I wish you the best of luck, it's an awesome ship, though not having a measurement on the image might set you back quite a fair way. There might be another program you could use that would still maintain the image integrity?
I really like this ship. I keep looking at the competition I'm up against and somehow I always come back to this one. Really good shape to it. Hope it gets through!
great design. you shout improve the layout of your presentation. maybe remove de drop shadows and the line of the horizon. remember to use the 6 views.
Try using the GIMP to overlay some scale information and minimalist decoration.
Good luck, you have a following here already - I vote focus on this design, don't move on to a new one!
Rock on dude. :{>
