One suggestion. Move a little closer and do it from a seated position. I think that gives you more control and less movement so you can see more clearly vs. trying to do a windup or even just pitching from your feet (not sure how you front-toss, sitting or standing).
Beyond that, just think about what she is trying to accomplish with the RESULT. You can learn and work on a lot with that. Is she early and slow loading? Is she hitting the ball where pitched? Mix in some changeups...how does she handle them? Mix in some fake throws -- has she started her load or is she standing flat-footed? Plus I DO think you can see a lot of mechanics from the front, they just look.....well, different, ie from a different angle
