I wish I could see that in slow mo. I put in on pause and tried advancing through it like that. There are a couple of things I definitely picked up but there's another thing that I don't feel I can be sure about but seems rather a major thing to me.
For definite she initially reaches up, then lets her arms drop, then tries to pull her shoulder angle back open just before her hands hit the floor. I would think that would make for a less reliably open shoulder angle than if she maintained the position of her arms in relation to her trunk from the instant she first lifts them. Also her arms are not quite close in when her hands are on the floor, particularly the right one which is slightly bent. I think that probably relates to what BlairBob said about her arms coming wide as she returns to feet.
The other thing that I'm not sure about: Does she do a weird double hurdle? Like she takes this really big hurdle, lands back on the same foot and does this little skip step into the handspring. That's really got to kill momentum and make for poor heel drive.
