This is one creepy piece that somehow attracts me to look deeper into it.
I really like the surrealism and the details. They are very well drawn, and makes the picture too realistic. The colors are great. Somehow reminds me of old sci-fi comics, or Neon Flux (old anime, I suppose) that I have seen on Mtv. The tongues are looking like they were dancing in sick harmony. Love it.
The girls nose and the upper lip is slight too long. It makes it look like a birds nose. But everything else is really Nicely drawn.
And, yeah, the early hours in the morning/ night are the best for producing great works. This is one great example of this phenomenon.
