Tank Tracks Animation

I've animated the tracks and worked a bit on the back of the tank. It looks okay, the animation works quite well. Its been rendered using mental ray, but the quality has been reduced to upload on here.

I've finished the lower half of the tank and uploaded some pics of it below. The next stage is to model the barrels on the back, and create the top part of the tank including the turret and add any lil bits of detail here and there. Hopefully it will be finished soon! Then I can start blowing stuff up. cool beans!
