I put in another 4 hours work on this last evening. I had to make a correction to the chin area...I seem to have gotten lost while working on the whiskers. I've also worked on the overall depth of the hair shading...it is coming along layer by layer. I am concentrating on not getting in a rush, trying to take my time and get as much out of the shading process as I can before moving on to the other side of the face.
