Really good! There's so much I like about this swing. I love the way she uses her core with her hips opening as she gets to foot-down. This is an area that my DD can improve.
Sorry, barrel path should be a little more vertical as a clock face going from 12 - 6. These swing are more like 3 - 9. The difference being your daughter's swing is around the front leg and the hitter I posted is around the rear leg. The hand action must be that of swiveling the barrel and not pulling/pushing the handle. Hope that makes sense and that you understand that I am not criticizing just offering advice. She can obviously rake.
Here are a couple of others with a 12-6 barrel path
She has excellent body actions. To get her to use her hands better/tighten hand pivot point/get more 12/6 in swing have her play around with her top hand in her setup....right now the top of her fist is pointing at the pitcher in set up and her top wrist is largely unbent/un-laid-back. Vrooom her grip so that more of her palm shows to the pitcher while keeping her current elbow position. (In other words, dorsiflex her top hand wrist). Right now her top hand is too "strong." What I proscribed should help her work toward a pivot point that is tighter around her hands, get more 12/6 and get her barrel deeper.
(Another way to accomplish this -- though it often is used in ways I don't like -- is to check her knuckle alignment in grip. The spectrum goes 1) punching knuckles aligned and wrists "straight" to 2) box grip with "opposite knuckles aligned" to 3) knocking knuckles aligned). Your DD should play with moving from knuckle position 1 + aligned toward position 3 with top wrist more "laid back" or dorsiflexed....likely settling for some comfortable spot in between likely closer to position 2.)
