You know Wilt, this is a really interesting piece - you have nailed the SSS to such an extent that it looks alive. The form of the girl, however, is sufficiently inhuman that she looks creepy - I think you've hit the uncanny valley here.
Which is in fact a sign that it's close to perfect.....
It's kind of wierd for me because I don't usually get the uncanny valley creepiness sensation but this time I do. I think it's the ears. ;->
