You look like a very good, capable rider and I love your horse :)
Let me just offer a tiny bit of advice that I'm working on. You seem to be jumping ahead, which everyone knows is baaaad juju. Try to stay back and wait. Your horse will lift you out of the saddle. Ride like there's no jump there. Like you're just cantering about. There is no jump. Ignore it.
Otherwise, we get these stiff, odd looking jumps that don't benefit you or your horse and then it's all sad. :(
Happy Eventing!
