Overall her action is pretty good and I have seen plenty of pitchers make this work. I don't think it's necessarily FSR that needs to improve, it's more her posture at landing and release, she's very upright, even forward a bit and I'll bet a rear view would show a hint of monkey butt. I would do some long toss with a cue of staying tall at landing. When doing long toss a pitcher will focus on throwing the ball higher (part of throwing it further), it's important that she do this by leaning back and not just holding on to the ball longer.
