Thank you for everyone's effort, but I'm sad to say that no face isn't me. =w= I didn't have a large mouth in the middle. ;A; I'm sorry!
Oh! While I'm replying,
Here's my set of photos. I only have pictures from Saturday and Sunday, so see if you're in there.
(For a reference to MY no-face cosplay, it's the second to last picture. I'd like to see if there's one out there taken by someone else, of course ~ )
