Robert Liberace's class. I have learned a lot in this class. The one lesson that stands out the most, for me, was learning to slow down and look carefully. I had lost that in trying to get information in quickly but then miss subtleties that can really make a painting sing. This is a fine balance because the danger in slowing down can also go towards being "overworked". This is one of the common problems in art, knowing when to stop.
I am going to put this one up for auction on the Daily Paintworks site when it is posted tomorrow.
