I looked at your other drawings. They are all very good. Do some study on hands & feet. Also, consider adding some shading (muscle structure) to give your drawings 3-D solidity. It will add to there impact. Keep drawing. Practice makes better.
it's been a while, but thanks, man. will do hands and feet -- i love drawing hands, feet not so much. i think they can say a lot about you and are very interesting.
as for shading, hah, i'll try. i get frustrated, it takes a long time, but i'll do it.
