Definitely creepy and cool...
However, I'm wondering about the proportions. It kind of looks to me like a rabbit head on a human skeleton.
Would if be of benefit for it to be slightly more squat, with a larger ribcage? And the leg bones definitely aren't rabbit-like, though the feet are a bit that way (and I can see the tailbone is extended).
That said, if you're going for a far more anthropomorphic, humanoid character, then that's all well and good, though it's not what I would personally expect. Perhaps it's a bit more like a Bugs Bunny rabbit?
I like the bone ears though - they make perfect sense to me
