This is the big points I see:
-you have a nice steady leg all over, on jump, flat, etc., but I would like to see you sinking down into your heels (heels down, toe up) a little more. And, remember to keep your leg in a straight line from your ear, shoulder, hip, and heel when on the flat.
-give, give, give! While cantering around at the flat, your hands were bouncing around, up and down, side to side, and not following your horses head. You want your hands to follow with your horse's movement, not restricting. So, work on steadying your hands on the flat and going with your horse's head movement. Right before a jump your hands bounce a good 10 inches or so up and down a couple times, which off balances and distracts your horse, not to mention you bop him in the mouth. Attached photo shows where your hands are (red dot) and where they should be (blue dot). You also want to put your hands a little bit more together. Going over the jump, RELEASE! You are bumping him mid jump, which, again, makes them off balanced, distracts them, and they learn that if every time they jump they get bumped in the mouth you are telling them not to jump because you are bumping them, right? Or that they learn that if they don't jump their mouth wont get bumped. I would recommend jumping with a driving rein for a little bit (http://prairienerd.files.wordpress.c...pg?w=516&h=385
) until you feel you have following your horse over the jump down. Driving rein helps teach you to follow the horses mouth.
-you are jumping before the horse. Sit back, don't anticipate, wait for your horse to jump up under you. For this, close your eyes right before jumping, and just feel the horse and let him thrust you into jumping position. You can't know when your horse is going to jump, you have to let him tell you - otherwise it becomes a bad habit, gets your horse off balance, teaches him to speed up before a jump, take off weird, and its just plain dangerous because if your horse decided to stop before a jump, odds are you go sailing over his head.
-keep your back flat, pull your shoulder blades together, and shoulders back as you are hunching your back as you go over the jump.
You have a fantastic horse, and you have a great foundation, happy jumping!
