Since it is not the technical forum and Eric is doing a fine job. The one thing I would suggest is bringing the bat up above her shoulder to the neck slot instead of below the shoulder. Her speed....just looks like she isn't swinging as hard as she can. Speed up the pitch and see what happens.
Neck slot ala Caitlyn Benji.
I really like this and actually have a few of my players swinging this way. Others will have their hands slightly closer to the shoulder and a little higher.
