I am starting to enjoy this portrait. I haven't done oil for such a long time but I am getting back in the swing of it. I disagree with the salesman at Dick Blick and I still think you need a blending medium even with the water based oil.  So back to Blicks I go for more paint, blending medium and a few more brushes . I need a few more blending and fine liner brushes so I can put his bangs back in the portrait.
