Looks to me from the video that she is leaning way back and never gets off her back side. Her swing seems to be arm/hand-driven - no real body helping to propel the bat. Any turn she gets is follow-through. The hips should lead, followed by the shoulders, followed by the bat.
Watch her back foot. It doesn't look like it gets fully turned until after contact. That should happen before contact.
At toe touch her front shoulder should be lower than her back shoulder. It's the opposite - more indication of her staying on the back side instead of shifting her weight/momentum into the ball. I'd probably fix that first and see if it helps some of the other issues.
