Primary colors

Inspired by various online painting challenges where you paint a subject using only primary colors (and black and white) ... here's a small (about 5x7) lunch-time doodle. After recently watching this clip from the Leno show (it's a hoot! http://www.lolbucket.com/video/KN5K8Y4S1AMA/100-year-old-Idaho-woman-on-Jay-Leno-show ), I wanted to capture Dorothy in her younger years - Jay briefly shows a photo in the video. I can see I really need to pay attention to the placement of the eye closest to the viewer - it seems a little bit high and too far outside, again!
