I absolutely love the first headshot. Shouldbn't his ears protrude from the sides of his head tho? I'm pretty sure all of Toriyama's ears were visible from the front view.
Odd...the side view head has everything in the right place...but its deformed for some reason...
the top of the cranium needs to be lowered and moved to the left. The face should be brought up a bit, the ear is way too big. Just move stuff around till it fits a more...cranial looking appearance...I'll try and do a drawover soon.
About the ear...isn't it common for anime ears to only be as high as the top of the characters eye and as low as the end of the characters nose? thought thats how it went...I may be wrong though.
Keep it up though, awesome model so far.
