I used to work for a military contractor and one thing I think you really need to reconsider are the spoked wheels. I know you're going for the cool factor and your wheels do look cool, but spoked wheels fill with mud and become unbalanced. Another thing that happens is debris like branches or stones get stuck between the spokes and cause problems.
As for the model itself, it's cool. Reminds me of 'Damnation Alley'. (The book, not the movie.) Nice work and I will keep an eye out for more of your stuff.
