Excellent! That hair really turned out. He does seem a little "poofy" though. It seems like his hair should lay down more. THis is just opinion though, and I think it look great just like it is.
Add reflection to the car so it reflects the surrounding. You might want to play with spec size as well. Try size:80, intensity: 150 and go from there .
Looking good except for a few lump here and there.
