I could be definitely wrong, but it looks like you jump ahead. While at first glance you look alright in the jumping picture, it seems like you're thrusting yourself out of the saddle and up your horse's neck, rather than waiting for him to come up to you. Like I said though, I could be wrong and it may just be the picture.
On another note though, your release is decent, just try to relax your arms a bit and make sure your hands are pressed into your horse's neck, not hovering above it. Overall nice job! :)
