You are a very good rider. The only thing I noticed is that, like horsea said, your hands are extremely busy. Try to keep them lower on your horse's neck and quieter. Right now they are up in the air and moving all over the place. Also, is it just me, or are your stirrups too long? It's kind of hard to see. But, try shortening them a hole or two and see what happens. Right now, your legs are wobbling. Shorter stirrups help you push down your heels and keep a firmer leg in place.
Other than that, you are an amazing rider. Good job, and keep it up!
