You are overjumping a little but your eq is good so it can be easily fixed. Your release is good and if you stop overjumping, your leg should come a little more towards the girth, but you have a good leg.
I'd have to disagree with the first few comments, I quite like your position and I don't know where they're from but over here in Canada that's what you'd want. I'd say the position is a bit low for the jump height but that's totally fine, next time when approaching the fence just sit your butt lightly in the saddle & let the jump come to you, don't antisipate the fence too much, that's a major cause for false positioning, but I love your flat back, and your release, just remember to keep your leg underneath you more or you're going to set your horse onto the forehand and that could cause a problem. I like it! :)
Um.....I don't know what circut you do in Canada, but that isn't the position that you want "in Canada". I agree with everything said before. You are overjumping and are laying on your horse's neck. You need to sit up a bit and let him do the jumping. You are there to go with him and to support. I like how close you are to the saddle; you look very relaxed. Your leg has slipped back, all you need to do is sit up, pull your leg forward and you'll have a really solid position.
