Let me clear some confusion for you.
Ballet is TOTALLY different style from contemporary. Shakti is absolutely not trained in Ballet and it usually takes a person their entire life to lean ballet... Kids start when they are 2-3 years old. So for her to pull that off on one week was AMAZING! Terrence did not give her a style that she was familiar or comfortable in, but rather one that she has never attempted once in this competition. Just because it "looks" same to you does not mean that they are same and it definitely does not mean that it is easier for the contestant!
Plus I would really like to know, on what basis are you calling Shakti ugly?
