Critique ridding and horse!?

You are perching. Sit vertically, lengthen your stirrups two holes when you are not working over fences and stretch your heels down and your shoulders back. Turn your thumbs to the sky and keep your hands more together so they don't move so much. You need to give him more warning when you ask for a turn, use leg (calf) first and you may not even need rein, he responds to you pretty well. Your back is hallow, but sitting up straighter should fix that. The horse looks much more relaxed and stretched out so you are progressing nicely :-) At the canter you are using your upper body to absorb the motion, so either ride it with your hips by sitting in the saddle or go completely into 2 point and remain still. That half-position is non-productive and causes some motion that is unnecessary. I know I sound critical here, but I am just laying out what you need to correct, because you have a nice way with that horse and these really are simple things that you can fix in very short amount of time practicing! I really wish all the best to you, seems like you have a promising partnership there!
