Ive been working on trying to stay with the motion and not get ahead of it, guess I still have some more work to do!
By over jumping do you mean too much release, too far forward, or?
Also, does it look like im gripping with my knees? Or are they alright like they are?
First picture - heels down. You are gripping with your knee and since this means you aren't sinking your weight into your heels, they're up. If you stop pinching at the knee it will also help you stay with the motion of the horse because you'll have no knee grip to push yourself off with. Just keep your weight on your heels and your horse will boost you into position. As a result of you being ahead of your horse, your hands are too far up his neck. You want a straight line bit-hands-shoulder.
Second picture - you're still pinching, but you're not *AS* far ahead of your horse. Try to settle your crotch right above the twist in your saddle. If you're at the pommel and something goes wrong, you're going to go flying over his head.
Third picture - I really like this picture, even though you still need to learn to sink on your heels and your toes are out. I also find your knee a little high where it makes contact with your knee roll, but that's not a big deal.
Overall I think you look very very good, your horse looks quite honest and fun to ride. :)
