Hm,

I don't know, somehow I can't like this picture. He looks stoned here, and she... her arm is twisted in a strange way, again the fully drawn outline of her forearm is adding to the effect IMO. Also, somehow I'd expect him and her facing each other when he is teaching her. her head also turned out a bit small, but that might be due to perspective and him being as big as he is in the background. Not by any means horrible, but I can't say it's a favourite.
