I like the idea of entry #4. I wouldn't mind seeing different font from what I already have on my website, but like the ribbons off of the E. Not sure about that exact dancer image. I like swirly things and something a bit more abstract. I feel that makes it look like a ballet studio and we do everything.
Generally speaking I'm not 100% sure I want a dancer in the picture, I'm not against it either it just has to be the right one.
I like the swirly sort of effect of #6&7, but i'm thinking a little more abstract. I think I am looking to see something that is just different from the simple basic one on my website.
