This looks awesome. Is the background an image? If not, than you did an awesome modeling job of the environment. If so, than it's a great compositing job.

It's a compositing with a photo. thank you!

Awesome model and textures, but the lighting needs some work. I think the Blender Internal renderer has met it's limit here, so consider using something like Cycles or luxrender to get it more realistic. If you do this, no one will believe that it's CG ;)

@gregzaal: thankyou. I'll try some renders with them! I think you're right. @Gikkio: thankyou for the visit here! Ahah! :)

this is fricken awesome!~!!!!!~ may i use it as scnery in one of my maps ill give atmost full creditss

is there a way to make the tracks turn and make the tank move

Genial!!!

I think that this post is one of the only that looks realistic. Good Job of Texturing the Beast.
