I was really just focusing on rhythm and relaxation so my reins were a bit long. I can see now that I can easily shorten them a good six inches and he won't fuss about it. I like the first section a lot; we were working on turns on the haunches and moving sideways. My left lead canter depart happened off camera, but I caught the right lead depart, and I am so happy with how smooth it looks.
Overall, he looks relaxed and happy and ready for more difficult work. If you search around in the archives, you can find some footage of him being really naughty. Clearly we have improved!
