This is an update of my previous blend, and I'd say it's far improved. I made the hands less organic, and more similar to the rest of the body. The rig and textures have a few improvements (bone shapes), and I also gave him a minigun.
I don't care what you do with it, but if it's noteworthy tell me, I'd like to see this guy in action.
Be aware, it has about 800,000 verts rendered, 300,000 viewport, but if you leave simplify on it shouldn't be a problem
