I've only been in an English saddle for less than a month and only been riding at all since the spring. I know my canter is not very good, but this was literally the second time I ever cantered in my life. I'm better than I was the first time! And I can see I should also relax my forearms, I hadn't noticed I was doing that until just now watching the video.
Any feedback is welcome! Thanks a lot guys :) I'm a big newbie, so I can use all the help I can get.
