How to Draw the Lips and Ears

Stan Prokopenko has nearly finished his amazing 'How to Draw the Human Head' series, with the lips and ears installments.

I've really been enjoying these videos! Be sure to take some time and go through them if you haven't already. Personally, it has really helped me have a deeper understanding of WHY I am drawing the things I do.
