lookin lots better , here are some things i think might make it look nicer, the forehead needs to be smoothed out a little, i think that area is too sharp. also his chin looks a little odd, looks like people do when they align their top and bottom front teeth up by bringing their bottom jaw forward, heres a pic of the last model head i made, it might make it easier for you so see what i mean (mine isnt perfect but its my best try so far i think my forehead is a little too rounded tho ) end excuse the messy bit round the ear
