I am really beginning to enjoy this piece. She is really coming to life. Faces do not have all of the creases and minute details that one experiences when drawing hands... Much more of a free flowing atmosphere in the studio.
The hair is making its appearance into the composition with the introduction of the eyebrows and hairline. I am not sure that the rest of the hair will be as relaxing as the facial features, but it has got to be better than dealing with animal fur! ;)
Here is a little comparison with the reference photo. Sorry for the glare, but the lights of my studio can be a real pain!
