Self consciousness I guess. Many people are told that they are photogenic all their lives. I have never been told that. Or that I am handsome. Actually, online, I have been told that twice! I was rather surprised and happy with that.
But when it comes to a picture, I only see flaws. But I feel I must try at least once to see how it works out.
Other artists I have talked with say it is part of the process of learning.
So I will draw it this week. From this picture, and I will try not to tear up the paper in disgust.
Now if I can erase that second chin!
