40K Style Orc WIP

So there I was playing Warhammer 40K some years ago, thinking about how much fun it'd be to do my own Orc, with a fuel tank, and combination claw / flamethrower mechanical arm. This is before Dawn of War existed, so I thought it might be cool to see what these characters would look in a real time 3D sort of way. It's likely that if I finish this guy, I'm just gonna rebuild him altogether, play with proportions, details, etc. I might even completely re-interpret the Orc face to my own liking, rather than going with a traditional 40K style Orc.
