Gracie did not have a good start in Canada, but she still had a lot of good qualities to be positive about. I like her speed on the ice, she has good edging, lots of height on her jumps, as well as distance. I think she needs to work on her posture a bit and her artistry, however, she is very musical. And her 3lutz3toe is awesome.
Caroline Zhang really needs to work on her speed, and that double axel technique is unacceptable. There's no jump into it, and lands it at a stand still. Just not good.
Christina Gao is a great jumper but also needs to work on her speed and transitions. Her 2axel technique could also use some work. She does not jump into it as well as she does with her other jumps. Same problem as Zhang's; lands it with no speed or flow. Christina could also work on the technique of her 3salchow. It's a bit awkward.
I think the top American lady currently is Ashley Wagner. She has become the complete package skater. And if Agnes Zawadski got herself together, she'd be pretty tough to beat and probably the best skater in North America.
