Always a great video to compare to. Now not many do the same backswing as her, but just about every other part of the pitch is worth emulating.Her arm action looks much improved. It looks like she's throwing bullet/gyro but that is not a concern for me at this point and just a statement of fact. The next area to work on is her posture. She has a strong launch but my feeling is that she leans forward a little too much at takeoff. The effect of this is that her hips never catch up and get ahead of her shoulders. A pitcher should feel like she is leaning forward a little at takeoff and back a little at landing. If you look at this video of Amanda Scarborough you will see what I am talking about.
Compare your daughters spine angle when she has the ball at 6 o'clock (windup not release) with Amanda's spine angle and you will see a significant difference. Amanda bends over at a lot but straightens up at takeoff. Notice how when Amanda lands she is tipped back. Try standing a little taller at launch and see what happens. This should also help keep her back foot down. Note: look at the ball after Amanda releases it and you will see bullet spin.
