In my view, the benefit of shooting your daughter and doing so repeatedly is that you can learn her routine to the point where you can breath it. This should help you quite a bit with getting shots that capture the best portions of the routine. Look for the most beautiful poses, the most graceful movements, and peak activity. Not all will end up as great shots, but not bothering to shoot during the brief portions that won't ever lead to nice photos will go a long way toward improving your keeper rate. These look nice, and as already noted, backgrounds are important. You could crop that first shot to eliminate all but the black curtain background.
Keep at it and keep posting, and welcome to the Sports Corner.
