I typically draw with ink then go right to the paints. I never sketch with a pencil. I surprised myself that I could achieve this with a pencil and a blending stump. Pam's "face mapping" is ingenious and the structure of what I learned has definately transferred to painting portraits for me. If you want to know what face mapping is you'll have to take her "Still Pursuing Portraits" class at Artful Gathering 2013.
See some of my older posts here, June2012 to see more sketches from Pam's class.

It's a whole lot of summer studio fun over at Artful Gathering,
