Again..
Pretty good work here. A few issues with this one though. Where you have the black between the inside of the lip to the first tooth it suggest that the teeth are starting to curve around. However, if you look at the face and the jaw you'll see that the teeth shouldn't start curving around that particular spot.
Actually... looking at it a little bit more the teeth should start the curve but the shading should be relatively light where you instead have it as complete black. The left shoulder blade should have more shading to show the true depth. It looks sort of strange, but I know where you were going with this. The middle finger of the right hand seems like it's attached to the pinkie finger. I would say darker shading in that area would alleviate the trickery that meets the eye :) . The hair is fantastic! Other than the issues mentioned above, impressive work!
