I would address the level-shoulders swing flaw ... and when I do this I generally include an emphasis on the swing plane, which IMO is need of being addressed for this girl.
This is a very common swing in FP. This is my definition of a hybrid type swing and is a good example of how coaches are teaching kids conflicting information. This is the swing you get when the instructor/coach combines the following cues:
Swing level/down to the ball
Take the hands to the ball
Turn your hips
Keep your weight back.
I hear these cues all the time when I'm at the cages. All the time!
I would say this player is performing those cues really well. The problem is the cues can't coexist. What you end up with is an upper body arm-y gate swing that looks better than it is because the player has been taught to turn her hips to dress up the linear hands-to-the-ball upper body mechanics. The hip turn is purely cosmetic.
I find players with these types swings easy to work with because they have been taught to keep their weight back and therefore don't lunge. One less habit to break. She would pick up on Esptein's Torque Drill in no time. This would fix her level shoulder issue and give her IMO, a correct image and feel of how the shoulders should move.
Adding in the correct hand flattening movement would help fix other issues including creating more separation and keeping the hands from dropping prior to launch.
