One of the better warthog conversions I've seen on here. I'm working on one at the moment. I'd recommend spacing the wheel farther apart wider, and giving them wheel wells. And I used a piece of clear plastic cut into the shape of the windshield. Other than that, awesome work.
i really like your Halo theme, these and the scorpion, id' like to se if you could make a general as Master cheif, would be cool if you could pull it off :)
