Anyway, it's alright. The bottom of the head seems very, very flat, though. Are you chubby? Because although the sides of the head aren't very chubby, the whole shape of the head implies chubiness. Also, outlining darker shades with lighter ones doesn't seem right with whatever lighting you're using here. It looks like the light source is above and slightly in front of the head? Given the number of shades you're using, it could definitely use some more AA'ing as well, especially on the line borders.
