Check out this super cool Tumblr! The blog has cast cosplayers as SU characters. They answer the questions with a gif of themselves, and a written answer. As it states on their first post, this is a human alternate universe, so of course gem characters are not going to be show accurate - rather, they'll be a human representation of that character.
They opened auditions for characters when the blog first opened, and as new characters are introduced, they are being added! There even appear to be some roles open, so if you're looking to audition, it's not too late! This is a really cool idea, and the ask blog is super active. Be sure to check this one out!
