[SR Note: I have no idea if something like this would even have a place on my back piece or not. However, I do think it is a very cool samurai hoshi-bachi kabuki and skull. I'm open to having a discussion.
This image gives inspiration for the skin and mood of caliban. I like the skull look, but yet it is more human than a skeleton, and that is kinda what I want in caliban. A pirate that is a mix between human and skeleton or monster.
