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.
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.
