I think I've done as much as I want to on this. I'm not happy with the effect of the forehead where I tried to correct the shadow. Maybe I should have just left it as it was. Not to worry. Boy, I look miserable. But I'm not really.
Okay, the next self portrait I do will be of a 'happy' me.
I may go back and make the eyes as dark as the jumper. I'm happy with the hair and the ear, and the soft shape of the jumper matches my puffy face (Post-Christmas Bloat would be an apt title for this).
I like the general pose I've used here, and I think the proportions are fine, so I may use this as a basis for a much bigger drawing. This is A3 size, so I may make a start on an A1-sized drawing next.
