Well, today's drawing took a lot longer to complete than yesterday's.  The likeness disappeared about half way through and I came very close to hitting the delete button.  But I persevered with it and it got a lot better, although I'm still not 100% happy with it.  The mouth is not quite right somehow and the eyes are possibly a bit too wide. The temptation is to go back and tinker with it, which I'm doing my best to ignore.
