Hi Scott,
the wonderfull thing about ZBrush is that you can work any way you want. In other mediums clay for example to make a change like reducing the bulk in, say the face, means loosing all of the detail in that area. But with ZB it’s all still there! I never take that for granted.
You are right about the left knee, it was just a very quick edit that I did;)
I think you mentioned a little while ago something about spending a long time on a work like this that you can lose objectivity because you are so used with the way it looks. One thing I like to do (works well for faces) is to turn the model upside down. This fools your brain giving you a fresh perspective and you can see proportional differences that you may have missed before.
I am nearing completion of a bust of Lance Henriksen (I posted a WIP early last year) As you may have guessed he is rendered with 32bit displacement mapps in mental ray. He has the fast skin shader and dynamic hair (I hope to make him talk) I would apprecioate your comments when I finish him.
Look forward to seeing this dude after you make your ammendments.
Cheers,
Shadowfiend.
