Wow, thanks for the comments so far!
I turned the head away just a tiny bit when he's firing the pistol, it'll still take some tweaking. Also fixed the boot up when he steps forward.
As for the smoke, I don't really remember why I put it in originally, but I liked it, and later on decided he's probably smoking inside his helmet, it's just venting the smoke for him. I'm trying to figure out what exactly I should do with it, I might just get rid of it entirely. I'd think it'd be rather unwise to smoke inside a helmet like that.
\/ That was another possibility I considered, though if that were the case, him breathing between every burst of gunfire would make the most sense.
