Cute mare! It's hard to critique a horse's jumping form with just 1 picture, especially if she chose that 1 picture to not look her best! It looks like she's using her head and neck and rounding over the fence... but her front legs are not ideal. And that's something major that judges look at! You want a horse to snap their knees high and square with each other and tuck their lower legs. She just may not have been trying very hard over this fence or maybe the distance wasn't correct. So like I said, very hard to judge!
