I'm so sorry that the feedback I've given you has been near-identical on every audition, but it's the same problem occurring - you have a nice voice, it just doesn't suit this character, which is very unfortunate. And, of course, the mic quality. Thank you for auditioning!
Oh yeah, like I said I didn't expect to get any of the roles. I was mostly doing it for the experience, and, well, why not?
