Try doing rough clouds for the beard, and then smudging it on another layer, and turning the opacity down. You could do that for the hair, too. Also try throwing some noise onto the hair and beard, to make it look more rough. And on the staff, and other parts of the body, the fill isn't complete and has some open spaces near the edges. Try a higher tolerance for paint bucket/magic wand, to get the whole selection in. Nice work so far, though.
