I only have nitpicky things to say in the way of crits, overall the model's great.
First. It's kinda harda to tell with just a 3/4 view, but he looks kinda fat. Maybe its just the jacket adding in that weight to his torso, but I really thing he could be a bit slimmer/sleeker.
Second. Once again, could be a problem with the perspective, but the arms seem too short. On the other hand you could be modelling straight from the ortho's Kakashi, in which case I couldn't really say anything since the arms are too short in the drawings too >_>;
The toes look too tiny, and the fingers could use some definite shape to them; they look like really slim sausages atm >_>;;
Did you model the body first and then put the jacket on top of it, or did you model the body and jacket together? Because the underlying structure of the body isn't reading that well (e.g. the shoulders kinda get lost in the rest of the body, and jacket seems like it'd cut off entire sections of his upper torso).
And the hair must be less spiky and more wavey XD
Like I said, nitpicks, and definitely nothing that if left alone would make the model look horrible in the specialists or something. Just my opinions on where it might be further improved ^^;
