Well, she looks good. I would like to sit and catch her, to be able to tell more.
Simple corrections that she can try is - adjust on the rubber to avoid throwing wide. And then, make certain that she is not letting her release twist a bit, to miss wide. Thirdly, put her power line down, so we can see how she is lining up.
I would put her with a really good catcher and see if she can encourage her to become really accurate.
I'm not a pitching expert by no means but our PC harps about your drag foot not going behind the lead foot. When my DD does this the ball runs inside. Your DD foot goes a little behind her lead foot and her shoulders open a little and you have to throw around your front hip. IMO
If you can video her from behind in slo-mo, watch her back swing and position of her hands on the upswing at 3 o'clock. With some kids, any variance in the back swing and track of the arms on the upswing can lead to issues right left.
Have her practice throwing inside and outside. Have her throw one inside, and then one outside, and then one inside, etc. If she misses (e.g, she throws it down the middle rather than inside), make her keep trying until she throws it inside.
You might want to spend 15 to 30 minutes does just that drill.
When she tries to throw inside to a righty (my DD is lefty), she gets a funky spin on the ball like her fingers came around outside of the ball at release. I notice her hand on the inside of the ball at release, thumb behind ball but leading with pinky. Do I need to tweek the release some (Balswick likes thumb on top pointing toward catcher at release)? Gonna work on drive foot not anchoring down so much and stride foot landing more toes toward catcher
