Aww! Your horse is very cute. Listens very well to you as well! She has a beautiful transitioning from trot to canter! Although she does seem a little uncomfortable in parts of the video. Her canter looks very smooth, and she looks like a fun ride! You look great in the saddle, and very good posture.. If you were going into english equitation classes, they would say somethings along the lines of put your legs back a little more to even your legs with your shoulders, and point your toes more inward toward the horse when you ride. Your hands bounce around a little bit and you shouldn't be able to see them move at all when you ride. Other than that you two look like a perfect pair together! :)
A horse is the projection of peoples' dreams about themselves - strong, powerful, beautiful - and it has the capability of giving us escape from our mundane existence.
