hah, wow... really nice job so far. For a noobie this is great. The seats on the inside are done really nicely.. how you have the curves in the seat modelled as well... it seems you grasp organic modelling really well. The extreme machine itself is a great idea... and i love its treads.. but the shell is a bit rounded in areas.. thats about the only thing that could be worked on .. i love the idea though.. just needs some attatchments to make it more rigid... imo.
