Quoting Minifig Maniac
Cute! But one thing...Wizards. Must. Have. BEARDS!
Well... Most of stereotypical wizards actually have beards. But it doesn't mean that every wizard must have a beard. Well I'm just saying that it is not needed, but I think that THIS wizard would actually look better with a beard.
I like the hat, you managed to make it looked creased like material, rather that smooth. It looks good, although I must agree with Minifig Maniac, it does look a tad odd as a stereotypical wizard with no beard. :)
