Am absolutely biased here - I like her since she was 10 or 11 (and she is an exception as I usually don't pay a lot of attention to novices and juniors outside of top-5). She already had very decent skating skills, posture and lines at that age

I have seen her live several times after that - at Junior Nationals in 2016/17, at Senior nationals last year, at some small local events and etc - she always stood out with her skating skills, deep edges and musicality.
Last year she was going trough puberty and her jumps and skating seemed to be a little heavy, but this season she came back to her usual self
Even despite some errors, she was clearly the best one in terms of PCS yesterday, even through some jumps were telegraphed. And I liked her long program - well-choreographed, age-appropriate, really suits her style.
