An update to the progression of this painting.  I think this painting is close to completion, after about 5 weeks of work. 

I'm letting this one rest now, as working on it has inspired a bigger series of screaming faces.  I've enlisted fellow painters, friends, family and students to pose, and have begin work on several new pieces.  I'll post photos of these as they progress.

Here's a bigger picture of the nearly completed painting.
