Hair isn't for beginners, that's for sure, but if you're brave ad not afraid to fail, I agree with McClane,
more definition could save this peice.
As a concept for this char, he could stay a non-descript white marshmellow blob but have incredibly cool hair with cunning detail, just a funny contrast. Could be good practice for ya. The chops are too big/fat. The glinty sheen isn't executed well. Reference more anime pics, like sailor moon and all that crap. Those anime guys do the shiny hair really well. Give him some pimped out shades instead of hollow orifices. I'm not sure what facial expression you're going for - he looks inbred . . . no, he reminds me of Stimpy in a daze. Hope that's helpful, g.
