We had a character design/modeling/sculpting seminar a few moths ago... i thought I'd post soem of my WIP.
In this image you'll see the modelling progress in maya and Zbrush.
I wanted to create a nice big dude, to apply my anatomical knowledge to its fullest. I tried not to use any references, but some muscle groups are just to complex..
I eventually ended up texturing this guy in Zbrush too, eventhough their polypainting tools aren't as good as they should be..:S
I foud a very efficient way to paint realistic skin, layers, layers layers..:D a lot of fun!
Here you can see some SSS rendertests from maya.
