This is an old WIP I revisited recently. The base mesh was done in Maya, the detailing in Zbrush. I also did something like 80 % of the textures in Zbrush and the rest back in Maya. The shading, lighting and finally rendered in Maya.
Here's my last creation,my favorite hero Morganfreeman, my goal was to do a realistic portrait in 3d of a normal person, and trying to make him look alive.
I think doing cg character is always a challenge it has so many details we have do deal with to make it look real, it's fascinating how the human body is complex and subtil at the same time.
I did it using Maya, rendered with mental ray and zbrush for sculpting., Hope you like it.
