The mouth should be a little closer to the nose, and broaden the upper lip to the center of his pupils. the place on the lower lip that you see protruding starts a little inside those bondaries.
the neck is a bit too skinny, should start right behind the jaw bone. Texture wise, the upper lip is usually a bit darker than the lower, you have that but i think maybe a little bit more would give it a better more realistic feel. I dont know the name for the part, but the piece of cartilage between the nostrils needs to be pulled down a bit.
I cant tell from the pic, but if you want to do mouth movement correctly you should have 2 verts where the bottom and top lips met on the side.
Overall this model is great, especially for milkshape. these were just a few nit picky things, the only major problem i saw was the neck thing, and the eyes and nose were a bit too high. Everything is modelled correctly, basically just some good old fashioned vert pinching will get this guy looking great.
