ah, I actually have heterochromia, believe it or not! (it's just the central kind, where the middle of my iris is yellow and the outside is blue/grey).

Anyways, this one is rather creepy, and for those of you who know vocaloid, this is somewhat based off of len in the PV 'Dark Woods Circus'.

oh, and in case you may be wondering, the nasty black stuff near his head is barbed wire.
