This is a very gorgeous and haunting picture. I appreciate all the fine details in everything. I keep thinking this guy has a beard looking at it from this angle. I guess this guy kind of reminds me of Sephiroth. It's hard to make this mask NOT creepy. It all looks so realistic.
A lot of stuff like this goes into the Uncanny Valley. Therefore, it's unintentionally frightening. This works every way you could think. I especially like the stuff on his hand. It has a great title, too.
