That looks really great! can't wait to see it painted. I have been looking for some vehicles but there are very few about.
I've been making my own stuff, not nearly as cool as yours. I have been using Foamcore to make buildings and backdrops for my macross and Gundam kits, here is a truck I made again from the foamy stuff.
I got round the wheels by inventing a Gravmag drive system - no wheels needed!
