Whoa! Thanks for posting this GN. I've seen it listed but didn't realize it was designed to be an audition for a role on Glee!
You should watch it! They have guest stars for each week. Darren Criss for Episode 1, Idina Menzel for Episode 2 and Dot-Marie Jones for Episode 3 so far. Each week, they have a homework assignment (like Individuality, Theatricality and Vulnerability). TGP's pretty good!
