The smile is actually pretty good, better than mine and I've been drawing a long time... I should be better than I am, but I really like it. Oh, and it sort of looks like Harry Potter. A lot. XD I would work on the shape of the eyes a bit if you want a more realistic looks and turn the head at a different angle to get rid of that flat look for now. You can revisit the flat look from below later. I enjoyed this piece, keep up the good work!
