It's MindChamber!
It's hard to believe that this is an actual 3D test of any kind, it just looks so much like it could be an actual picture. It's always great for stuff to look realistic. MindChamber actually did eventually end up with a real statue like that. I'm not sure if he made it himself or not. I've been seeing this robot a lot in tributes to that guy. I think he might look a little skinny in this rendition, but it's still a very nice picture. You see a more cybernatic appearance of him.
One strong point is how you used the light to glisten off the robot. He even reflects off himself with the yellow shades around his chest. I like the crystal like structures in his back. They kind of look like spikes. I have always been a fan of sharp objects in drawings and those seem to stand out pretty well from the rest of his body.
