I'm a wildlife shooter so take this with a grain of salt. Looking good with what you have here Sandy, but maybe cropping them differently could be worth playing with. Maybe a bit more more space around the shots, thinking about the hands and feet mainly in being too close to the frame. If you really want good advise in here, Don takes some amazing shots of his daughters dance class and portraits of her. I'll make sure he sees this, if you want good advice and I'll tell him to keep it simple with not going overboard with the techie stuff 😉
All the best and still a lot better than I could do.
