haha not a group that you can just join (atm)
People get selected to be part of it ^.^
Anyway dude your c4dwork looks a lot better here and I like the blue lightspots
However the thing that I don't like is that the render does not fit with the background. His colours don't suit that bright blue colour and IMO his skin and hair could have been darkened a bit
The c4ds blend very well with the render (aside from the colour clash.)
So yeah man great improvement!
