Bad news. You probably know what it is.
You mentioned that you had an original concept of Revali in your head before recording. for him. When I read that, I thought that was a little weird. LoZ is a video game series in Japan, so the production team already made a concept of the world, characters, and ect. before the game is localized in other languages. Therefore, Revali already had a concept made for him by the creators. When you went to audition for him, didn't your director or whoever gave you a basic outline of his character?
