Check your proportions. I get the feeling that the top of the skull should be a bit larger overall. That makes the hair look a bit out of proportion, especially in the first two. (Remember that the thickness of the hair adds to the size of the skull.) In the third one the overall proportions of the hair look fine, but it looks like there is a gap between her forehead and hair where there shouldn't be one.
Overall, I like the third one the best, but the colors seem odd. The lighting on the hair doesn't seem to match the lighting of the rest.
