Good stuff to work with, luvsb. When she loads, add a coil of the hips which she'll hold through toe touch (it's referred to as "forward by coil" by some posters on here). She's got a good negative move (weight goes back in the load), so adding a hip coil is a minor tweak.
I would also encourage her to land on the inside of her front toe with a flexed knee, which will allow her to "finish" her hip rotation. It looks like she plants her front foot like a stake into the ground, which limits weight transfer from back to front in her swing. Think in terms of driving "through" the ball rather than "into" the ball. (I like to start from the bottom-up when teaching.)
Thank you straightleg and MountieSb. She is a college freshman home on break trying to bring a little more to the table when she gets back. She works hard and we will add these tweaks and I will post another video.
Put your mouse pointer on your DD's front foot. Then put your mouse on this hitters front foot. This hitters drive comes from her rear side not her front side. Forward by coil.
