Desert Wheels - 3D WIP

I was looking for a new personal project when I came across the Desert Wheels art by JakeParker  (hope he doesn't mind me using it)

So far I think it is going very well but I will be spending many many hours on the engine and mechanics, so that should be fun to do

I'm making this in 3Ds Max 2014

Please let me know what you think as an help is very much appreciated.

Thanks
