Caroline Zhang is only 15. She has plenty of time to try different styles if she wants to.
Yeah, no kidding! She just turned 15 last month, and hasn't even qualified age-wise for senior worlds yet. I can't believe that people are already complaining that she's not branching out! I mean, how many 15-year-old girls have already mastered interpreting even one type of music, as Caroline has done so comfortably with soft, lyrical pieces?
In terms of artistic presentation and musical interpretation, she has a ways to go, but that's not what she needs most to improve on right now. What she really needs is to get those triples fully rotated, get the flutz fixed, and add more speed to her skating. These are shortcomings that, if delayed, may haunt her for the rest of her skating career, whereas she can more easily improve on the presentation later on, when she's in her late teens and early 20's, and won't be able to add new technical skills easily anymore.
She states in her goals for the new season that she wants to pay more attention to the details of the choreography. That's admirable, but really, I hope that she will work on her speed and flutz more than anything else.
