I think what I found most appealing about your contest is that you wanted something unique, not trite.
Since your business is about you as an entertainer I thought it would be great to create a portrait/logo. (in addition to a hand written signature). It creates a personal touch while drawing in the viewer.
Well ....i think it needs to be more subtle ... i don't want it to look like a caricature ... Interesting twist though ... i look forward to see it evolve.
