I'm never quite sure how to draw the chin in profiles. There probably is a rule that I've forgotten. I always see things in my drawings that I can improve on and it makes me want to draw them over again, but I usually never do. I hate seeing flaws in my drawings. Like, I wish I drew the eyelid sharper and straightened the forehead out and I wish I had not made the jaw so small, etc. Overall, I like the drawing, but I can't help seeing the flaws.
