I haven't seen all the programs from all the ladies, but from what I saw:
First of all, really happy for Ashley Wagner! Well deserved! I was rooting for her to make the team, every year she is somewhere near but never in, she is one of the most succesful US skaters at the Grand Prix, but Nationals just never went well for her. And now she is a National champion, hopefully it will give her confidence and motivation. I really like her LP, nice choreography.
Alissa... Well, she is a beautiful skater and all, but I guess I'll never really like her because I can't stand these jumps. They are painful to watch even when she lands them. Loooong entrances, no transitions, very low and barely rotated. She also seems slow to me, but I've never seen her live, so I'm not sure. Another reason why I don't like Alissa is her programs. I hope she will at least try something different, all of her programs are the same for me.
Agnes Zawadzki is a powerful jumper but she still needs a lot of work on her PCS. I don't really like her programs and costumes. Still, nice jumps when she lands them.
Caroline Zhang was a nice surprise! She lost some weight and looks much better now, and obviously she's been working a lot on her jumps. Way to go! Her spins aren't the same they were when she was a tiny teen, but at least she still has her wonderful layback. I think if she'll continue to improve it's possible for her to make the team next seasons.
Mirai... Oh, what can I say? She has really nice SP and I hope she will keep it next season, but that's one of the programs that look brilliant only when performed good. And she needs to forget that LP and change it as soon as possible. Maybe she should work with different choreographer, I'm not impressed by Lori's works for her so far. But obviously, the programs aren't her main problem. She looks a bit out of shape. Maybe she needs to train harder, it's hard to say, but she is probably the most talented of all the ladies, such a shame to see her skating like this.
