I have blocked in the background to the hair leaving some texture. The is much more hair than is indicated, as can be seen in my original sketch below, but the hair is a golden blonde and the blocked in areas are only the contrasting darks over which the hair will be painted. It will also come much lower over the forehead and down by the ear which has also been blocked in during this session.
In my next session I shall add a little more colour to the face near the ear and add some eyelashes to the right eye (left on the painting) which will fall over the eyeball. I will also add the small hairs that come below the eye.
As I paint, I also make minor adjustments to the parts of the face already seemingly completed. This is because, as I look at the work, I notice small things that don't seem quite correct that I can't comfortably leave. I am also beginning to think about the coat and zipper. The coat will have a small amount of colour and is highly textured.
