The GAR Heavy Scout Speeder was created by combining a vintage GI Joe Artic Snowmobile and an old POtF Endor Speeder bike. The side armor with twin cannons was taken from a vintage Boba Fett Armored jet pack. I combined the best parts of all of them, and added lots of greebles to accomplish the final look.
as for the rider.... again, awesome. I know it's basically just a head swap but the paint apps look great... as great as you could do with that super bright pink! I'm thinking that maybe you should have made the girl's skin tone more pinkish to match her outfit and tone down the color of it a little bit... it's very overwhelming. And you said the skin tone is green? from the pics it looks like a pasty off-white, but that might just be me and my monitor....
