Well this picture is pretty small and it's hard to see details, but from what I can see it looks like you're jumping ahead of your horse. Just let the horse jump up to you, don't make a big move forward over it, that's what my trainer always says. You should also get your hands more out in front of you so that you can give a bigger release, it sort of looks like they're in your lap in that picture. Looks pretty good though, pretty horse!
It looks like you are jumping a little ahead of your horse, as said above. Your legs are slipping back. And you also look a little too much out of the saddle but that's JMO. Like I said I am not totally experienced with this.
Overall, it lookds really good! Your horse is very pretty!
