Oh noes, now they'll be bombing us while we poop! [/jokeseriouslydontwarnme]
And who in their right mind would put a toilet out in the desert? I mean seriously, who would go through all of the trouble? There's nothing but SAND in the desert, hence it's called the desert. I mean, if you just sorta squat down and do your thing, nobody would really care (unless they stepped in it muahahaha). And where's the toilet paper? I mean come on, am I supposed to use sand or something? That'd hurt like hell.
Hehe, it's a nice render though. I like the shadows, but the rest looks too dark. 9/10
