If I hadn't listened to your audition for Clay I would've assumed that you really are British! Maybe you are... Ah whatever, this audition is also brilliant (kudos for your accent, coming from a Brit, it's fantastic), like your other audition my concern is that you do sound quite a bit older than the character, but that isn't a bad thing at all! It may not fit for this character (unless you were to shift the pitch of your voice) but there definitely some older characters for you!
Thanks! No, I'm not British, but I love playing with accents occasionally. I think I can raise my pitch a little, but it sounds pretty breathy.
