I read an Interview with Aerbuch. He talked about Yulia and Elena in it, since he choreographed for both of them. He said things like:
"They are both amazing talents, but completely different.
Lipnitskaya is very reserved. She has a very mathematical mind, spins and elements are important to her, to deliver a good program.
Elena is very focused on the expressiveness and the dance itself, she sometimes does moves on her own and such, (therefore) it's a great pleasure as a choreographer to work with her, she has the god given ability to pass whatever she wants through her/to others in a very sincere way."
(Not all of it and not all the exact sentences, but that were the main points)
I think he gets it completely right here.
Elena's absolute strength is her expressiveness, she is so alive in her programs, you can tell that she is all about energy and emotions. The Russian field is so deep. .. but this ability could really set her apart.
Like Elena said, "everyone should try to have their own face" .. I guess she means their own way, their own thing by that, and I think this is hers
