You are over bending her a lot in your lateral movements. Try and keep her as straight as you can. I understand there are time when you are trying to soften her neck up but that is something to be worked on before lateral movements, not during.
I also see a lot of asking for movement and direction with your reins first rather than your legs, seat and upper body. Always ask with your legs first! If you always ask with the reins first or don't take the time to use your legs, your horse will always require you to ask with the reins first.
Starting around frame 3:05, what is going on here? Your legs are off her but you're asking her to back up? I know western is different from english, but if you want to back up with no leg pressure or rein pressure, you need to use your seat. You are leaning forward here. You're also using your reins to back up? When I was training western, you used your seat and legs to back them up with only reminders with the reins.
Otherwise, I really think you're doing a good job! I like that you are mixing it all up. Lots of activities for her to think about. Good job with working each of her body parts!
