Are you auditioning for undergrad or grad schools?
I'm in grad school now. Most of my classmates came in with great headshots, but not all. One guy in the class ahead of me got in using a photograph that looked like it was taken in a greenroom in front of a piece of artwork.
I think a good headshot is a good idea. Is that you in your avatar? Because if so, that looks great.
Basically, I agree with jake6970.
I starred in a short film called
Magnetic Personality. Check it out!
