Paul Newman - decisions, decisions...

I'm having huge difficulties deciding which version I want to use and if I'm done at all. Once I finished the pencil sketch, I was very satisfied with the outcome, but when looking at the original sketch as well as all these versions I've spent hours to make, I feel those hours have been wasted. Just look at the last one! He looks so yellow that he could be a Simpson-character!

I would love to hear what you guys think - does it look like him at all? And what can I do different?

I think I've worked so much on this one that I don't remember Newman's face anymore, and probably need a good night sleep to take another look at it tomorrow...
