Dont be so hard on yourself!
I would say that your arms look quite stiff and you need to to relax and bend your elbows more. Some of the trot pics you are rising quite high but your horse probably throws you quite high?
Your horse is beautiful

by the way.
At least people on this forum know that they have to work on their riding and care about their horses to do the best for them.
I always think that photos are hard to judge, video is great to watch back and see what you are doing.
One day I might be brave enough to post for critique on my riding, definately a lot of faults to be corrected for me
