I think you need more of a curve on the outside edge of his left hand. Where his hand and finger meet. A inward curve there. I wouldn't hurt also to spread that finger out more. As for the knee, if you want it facing up, you would have to move the knee up higher and show more of the bottom of the leg. Right now the knee is facing front and down a bit. And the top of the line for the stomach on his right needs to curve in more. To match the size of the stomach on the left. Hope this helps.
Art gives me a life of extreme challenge, frustration, accomplishment and contentment. Nothing less will do!
