I'm going through the entries, stopping at those images I feel have had the benefit of an unconventional eye and dwelling a little longer to try to see and appreciate what you saw. This is one of those images.
Positives: Smooth blur but with a great sense of texture too - that works. The subtle coloration is effective too - I hope you try that more often. The double mouth makes the image - it acts as an anchor to the rest of your face - otherwise there's a sense it may float away like a moonward weather balloon.
Critical stuff: Not really
Overall: Effective - ghostly without being creepy.
This made me stop and look longer before pressing on. Not sure why, but my eye found it intriguing. Making me slow down and look is always worth extra pointage.
