Hmmm, well he's already made a vampyroteuthis, not a mask, but in paper mache....I have a picture around somewhere. SOS is too obvious, I like the nipponites ammonite. It kind of reminds me of Princess Leia, or is it Padme? But overall, I think I have to vote for vampyroteuthis, even if he has already made it. It's just soooo cute!
