Although I notice the eyes look like two different styles - the character's right eye is more almond-shaped, while his left eye is sort of rectangular (or maybe trapezoidal... I could be making up words, now.) It probably happened because there's hair covering part of his right eye, for different reasons depending on which was drawn first.
After hands, pairs of eyes are the most frustrating thing to draw right, I think. But the shading is great! And his left hand looks pretty wicked. As always, interesting animu hair.
