It is really hard to see with the great distance from the camera.
I did notice that you have your hands way out in front of your core. They need to be more connected to your center of balance and strength; your core.
Put some bend in your elbow, get your arms down against your sides and bring your hands in closer to you.
When you turn your shoulders into the turn, your hands must stay right over the withers, so they dont turn but stay exactly in the same place in relation to the horse. They would only change if you picked up the inside rein and shortended it or moved it away from the horse in a "leading rein" motion.
I though you did very well on your change of direction on the trot circles and in general, I think you ride extremely well for a reride beginner adult. The appy is darling! You two will be showing this summer!
