Research on auditioning

After some research I have found some key-elements we cam include into the character-designs in the mime-animation to make it easier for the audience to understand that it is a mime doing an audition. The classic "mime-look" is quite easy to read;

Features like; facepaint, a hat of some kind and stripy clothes and white gloves are well known to us and adding this to the design clearly shows that it is in fact a mime.
But how do you show that it is a mime auditioning for a part and not just a mime performing his act?

As I mentioned in the beginning of this post I have found some key-elements that might help solve this problem.
Within the group we discussed that we could have a sign stating "audition today" or something similar in the beginning of the animation to easier get the point trough to the audience.

But, when the pieces are shown on their own, for instance as part of our showreel
(without the beginning and the sign showing) - how do we then make it clear that it is a mime auditioning for a part?

Well, after looking through a lot of images from different auditions I found that the people auditioning often have a number, a sticker or sign of some kind showing their ID for that audition. This is done so the people watching does not have to take notes of their name, but can re-watch the tape afterwards and find the actor through their number later on.
So by adding this to our mime-design I think it will be easier to understand that it is an audition. (Even without the off-screen sound.)

I'm including an image I made that shows examples of auditions and the
performers "wearing" numbers:
