I'm not sure that I _like_ this, but I'm intrigued by it, challenged by it, curious about it.
I really like the colour scheme, the background and the emphatic spikes. I think it is the face in the centre that I'm less sure about - the toothy grin doesn't seem to fit with the eyes, quite. Maybe the Cheshire Cat's grin has wandered into the picture all on its own! Creepy, though, which is rather nice. I don't really get a sense of evil from this, though - more a sort of failure to notice than any positive malice. The eyes and beak (?) look great. Maybe it is because it vaguely reminds me of an owl that I can't fit the teeth and grin in very well!
