I'm actually interested to see Kostner's Swan Lake. She has the long-limbed look of a Ballachine ballerina, and with the right choreography, I thing she could do a good job with it. At least she is trying something that is different for her, unlike Zhang, who is sticking with the same style she always uses.
She may have long limbs like the Balanchine ballerinas, but she sure doesn't have the grace and refinement. Carolina may be 21, but her skating still looks to me like that of a 14-year-old who has suddenly grown 6 inches and doesn't quite know what to do with those long, long legs and arms.
