Now I have the face completely filled in so I can make some adjustments. The curve on the forehead is bothering me. I ripped out where the two colors join and moved the line to make it softer. I will probably move the hair onto the forehead later, so I am not too worried about the little jag at the top.
I added a strong highlight to the lower lip just under the dark line where the lips meet. I used the lightest flesh color for this highlight.
I am not sure about the dark circle under her eye, I will wait to adjust that. Adding hair and a neck may make this look different.
