That picture of Kyran is incredible. I like the colors you chose for the hair--for some reason they make it look three-dimensional in this interesting way. And the expression in the eyes is very nice--the eyelid makes it look like his eyes are a bit at half-mast, kind of sleepy or sardonic or something--anyway, I like it. Also like the rendering of the nose and ear, that's not easy to do in lines (well, not for me :P ). 0.0 Seriously, this is one of my favorites among your portraits.
He's sexy-lookin'. >>
