This horse looks like a very capable jumper, but I like to see a little more scope on a hrose that jumps this height. He is a very nice horse though, from what I can see. In one of the picks he is uneven, but he makes up for it in the other picture, it could have just been the timing of the picture. The rider looks very loose int he tack. The stirrup length she has now is OK for flat work, but she needs to shorten them a whole or two when she jumps. Lots and lots and lots of no stirrup work for this rider. Her leg is very loose over these big fences. Try and work at leasst twice a week without stirrups, this will help improve her leg. To help with over jumping, stick her on a lunge line on a trustworthy horse, and have her ride with her eyes closed and arms out. Start just walking and trotting first, then move to the canter when she is comfortable. When she has mastered that, start over X's and small verticals. If you do this eith your eyes closed and arms out, it forces you to go with your horse and not over two-point. When you two point, you should be just bending at your hip and lifting your butt out of the saddle a few inches. Her back is relatively nice, it has a slight arch to it. She is kind of over releasing a little bit. You want to give your horse his head, but you also want some contact to remain so you have control upon landing. Equitation flaws and all, she looks like a very capable rider. She needs to correct these flaws though. Good equitation, no matter what discipline you ride, is the key to effective riding.
