1.) Look good. Like this audition means something to you. Wrinkle-free clothes are a good start; a non-greasy face helps, too.
2.) Come in dressed evoking the part you're auditioning for. You don't have to be literal, but give the essence of the part.
3.) Your audition on camera is on camera until the CD says cut. Don't you stop the audition prematurely when you've come to the end of your copy, stay in character until the CD says cut.

5.) Know a strong slate. Be prepared to not only for this project, but also with the ability to show who you are appropriately in the setting. A strong slate is confident, interesting, simple, and effortless.
