Hmm, I don't think 'creepy' is quite the right word for her. It's strange, because her pose and expression are both rather seductive, but her body is very childlike, so it seems more like she's precocious, which can be very disconcerting, especially in children, but not exactly creepy.

I find the greys to have more green in them than anything else--but that can always be an easy fix in programs like Photoshop, especially since this picture is in grey/black/and white.

As for the pose, I think it's wonderful, like I said, it gives her quite a precocious air--that and the big hair, which is wonderfully drawn. Your shading is very nice--I appreciate how the lines aren't willy-nilly, and go with the curve of the hair, or sleeve, or wherever it was that you were shading. The blue eye seems a little out of place, but that's generally the purpose for having a single bit of color in pics, right? So the only critique I can give is that I think her right eye is a little high, and I think it would have been better had her right arm showed, in some instance--I know that this pose would have it covered, but when things like arms or hands are hidden in a picture, it always seems like the artist is trying to hide them because they can't draw them--even if it is completely not the case! So that's really not your fault or problem at all... so anyways, I hope you found this critique helpful. I definetly like this pic. ;)
