I finally finished the hair with the help of the three Filbert Grainer brushes. I used six shades of brown, all mixed and not straight out of the tube. Otherwise the hair would have had a flat look instead of three dimensional.

In light gray, I shaded the reflections in the model's eyes. I want to paint the shirt/sweater next. Then I will come back to the eyebrows, lips and decide how dark to go with the reflections.
