This guy taught me more about drawing than every other teacher combined. There is not a better draftsman. You will never find a more giving and competent teacher. He is known for stressing the little things and doing each one well. This is a small oil sketch on a 12"x 16" panel of him squinting as he matches a color and value for his next brushstroke. I did this little one in preparation of doing a larger one later on.
If you are interested in learning to draw, look up Paul Davis and go to one of his workshops as soon as you can!
