If you can, try to get someone to take pictures of you jumping from the side, and make the pictures larger. I can see some points that need improvement but I am hesitant to critique because of the angle. I would, however, highly recommend against riding in sweatpants and sneakers especially when jumping. From what I can see, I would say you need a more solid lower leg and to keep your toes from slipping in the stirrups, and not to brace with your elbows. I can't really see this clearly but you appear to be jumping out of the tack more than you need to. Make sure you aren't catching him in the mouth on the landing. As for the horse, he looks a little grumpy/ears pinned but he tucks his front legs nicely, but he needs to take the jumps straight down the middle, which is something you can help him with.
