A little more tone added to the face and some under painting to the jacket. Once I have begun to add the hair, I shall blend the facial tones more smoothly on the exposed parts of the forehead. I toned down the 'glistening' in the  upper lip and the crevice in the dimple under the nose.
As I have said before, I shall continuously alter some of the details in colour and tone as needed, as the painting progresses.
