Sharon and Bruce, you were both right about not using blue for shadows. I mixed up some burnt sienna, cad orange, and viridian green and glazed over the blues. Looks more natural now by comparison with the first post. Thanks for the tip. I also brought Sara's hair down over her left shoulder and put the tip in sunshine. Looks more balanced now.
Sharon, I have come out of the Witness Protection Program at long last! Feels good to just be me!
