This is great! This reminds me to tell you that it would be really cool if you could do you own version of the No-Face from Spirited Away in Lego! I would be easy for you since you're so talented with strange system builds.
But you yoursel could add so much style to it. You could make it look nothing like No-face and it would still be great. And I've seen other attempts at him. None can do what you can do once you have the idea to do it.
