Here's the next stage. I thought I was finished til I saw it reproduced here. I want to darken the background and correct the size of the mouth. I like the highlight down the side of the face, and darkening the background should make the paper colour on the face appear lighter. I don't want to use the brush pen to do that, but I'm not sure if the paper will take an ink wash. I may use soft pastels and cotton wool. And the shadow on the forehead is now too dark in relation to the rest, so that needs correcting somehow. I'm not sure yet if I'll darken the hair, or leave it sketchy. Mmmm. Time to go back and do some more. Yes, I think I'll continue working on this piece for a while yet.
