Great Action pic!
One thing that will help..
Your horse has a nice big jump. Jumper prospect for sure, she really found out how to get her feet up! To work with that kind of action- she would benefit from gymnastics. Spice up your riding with variations. Throw some poles around a turn and practice consistant bend and rhythm at the canter.
Try caveletti's before your jumps. Ground pole & jump variations so your horse has to watch his feet.
^All those kind of exercises will help your horse really work with her jump. It'll also help you just ride. She will carry you. This is where your auto release comes in. You've already got a nice crest release.
Going over raised poles, and jumping jumps in different angles and areas of the arena, will really help your horse get your leg and seat in sync with every next step!
Really nice horse. Post often! Hope I could help :)
