In myself, that is. When I first started working, I couldn't consistently keep Falko moving up through his back and stretching into the contact and roundness because I was so much in the hand (he's ridiculously light and quite sensitive) and now I can consistently ride him dressage! It's just a testament to how much good teaching and good horses can really make you a much better rider in a short amount of time!
Note: I'm not looking for critiques. That's what I have a coach for. I'm well aware of the issues in these photos.
