C4D is great, and the internal rendering is fantastic. The new Blender is no slouch though, most of what you can do in C4D you can do in Blender as well. I'm a huge fan of Bryce, one of the first programs I used.
awesome render. Very silver surfer-ish. It looks pretty realistic, or as realistic as a grey shiny guy in real life would look. And of course I recognize the BG from the hdri that comes with cinema 4d, but you did a nice job of actually showing it rather then just hiding it.
