After sitting across my studio looking at the painting for some time, I decided there were three things really wrong. (1) While the eye was okay, it wasn't working in the face as a whole. (2) The face was too small for the body. (3) The back was going off at too great an angle for the front legs and the neck.
Using titanium white I painted out part of the back and the ears and face (except for the eye), enlarging it at the same time. Then using Payne's grey I painted in the nose and the centre line down the front of the face.
Stepping back to look at it again, it seems the face is now too large for the body, but as it's turned slightly towards the viewer there would be some foreshortening, so I need to resist the temptation to make it smaller again at this stage. I need to wait until I've got the ears done and then reassess the size.
