I had this idea of a desert, like classic Egyptian desert, sand blowing all over the place, freaking terrible. But this sand, it's got all these bits of rust and tiny specks of metal in it. From the graveyard of tanks and oil towers and so on. I dunno, this is what happened when I explored it in my head. Hope you guys dig. The mask might actually be to filter out the rust and stuff in the air, I dunno.

Man, tanks are freaking HARD to draw. :P I actually used a 3d model as ref for this, I ain't even going to pretend I drew that from memory, lucky it is just an background element so I could be lazy.
