Here are a few quick studies from last Sunday's open studio in Florida. The seated front pose was about a half hour. The seated back pose was about 20 minutes and the standing pose was about 25 minutes. These were painted on a 20 x 24 canvas in oils. I usually get between 4 and six figures per canvas.
I used a very limited palette on these:
White, Yellow Ochre, Cad Red Med, Burnt Sienna, Burnt Umber, and Black.
