How to end my audition/monologue?
It sounds to me as if you are going through your monologue as yourself, not as a character in a play. In any play, but *particularly* in a period play, you need to figure out what the everyday assumptions are that such a real-life character would have, and impose any of them that are different from your own OVER your own ordinary assumptions. The judges don’t know when you are finished because you never break character at the end, like you’re supposed to. You are playing yourself, so there’s no “character” for you to break *from.* But don’t ham it up! — or overdo the “subsuming yourself in the character” stuff, of course. The differences between a dramatic character and your real self should be subtle, but real. As an example: Teenaged boys since prehistory have been horny and unwise, often pushy, where teenaged girls are concerned. Today, in the Western world, many/most teenaged boys can safely assume that they’ll be having sex with an interested girl sometime in the next few years.
