Fist Video: I can't see your lower half at all so I will critique as much as I see. You have a very nice flat back, but it looks like you have chicken elbows (when you're elbows go out to the side) try to keep you're elbows a bit closer to you're body. You also came back to early, while you're horse was still going over the jump. To fix that stay in two point longer until you're horses back feet are over the who entire jump.
Secound Video: The first fence you slightly jumped ahead of you're horse because you were trying to help her jump. You also came back just a tad to soon, but it was better than the first video. The striding between the two fences looked very short for you're horse so she had to put a lot of effort into jumping the seocund fence. When she jumped it she through you up out of the saddle which caused you're back to round and you're lower leg to swing back.
Third Video: The first fence it seemed like you were really worried going up to it. So when you reached the fence, instead of waiting for you're horse to rock back and push you out of the saddle you jumped ahead of her. Which caused you're lower leg to swing back and you're back to round. What I liked though was that you still released. By jumping ahead it caused you to come back to early. Again it was a really short distance for you're horse in between the two fences. To help you're horse get a better distance sit down in between the two fences and half hault. That makes it easier for you're horse to get over the secound fence. I am not for sure but it looks like you're leg slid back over the secound fence. And because you're horse had to try so hard it appears that she through you up out of the saddle again causing you to try and hold on so you rounded you're back and pinch with your knee.
Fourth Video: You're horse took the long spot to the first jump witch made her jump flat, so it was easy to get the right spot to the secound fence. But when you're horse took the long spot it looks like you got left behind just a little bit, which caused you to sit in the saddle to early. The secound fence looked a lot better though. You're horse finally got a nice spot that didn't through you out of the saddle. You could have release more which would have brought you're upper body down more. But I like how you're leg didn't swing back like before.
Fifth Video: You're horse took the long spot to the first fence but you stayed with her, which I like a lot, but you came back to early. The secound fence you're horse took flat, and it looks like you were a little surprised. you stayed with her nicely but you could have released a bit more. After that fence you had a very short distance and a pretty good distance. But instead of two pointing it looks like you stood straight up and kept you're arms straight.
Sixth Video: over the first fence you used you're horses mouth for balance by pulling back on the reins and not releasing. The secound fence you released better. And then you're horse had a really short distance to get over the third fence. Which caused you not to two point at all or release.
Seventh Video: First fence it looks like you were looking down at the fence the whole way to it. Like my trainer says don't look down if you don't want to be on the ground. ha ha ha. So try to look over the fence at a post or tree instead of at the ground. Again you looked down at the fence at fence number 2. If you're horse were to stop you probably would have jumped the jump all by yourself. I have learned from past experiences that it doesn't feel as nice without the horse. ha ha ha. Try to bring you lower leg more underneath you while jumping though. It doesn't slide back a lot but when you start jumping higher it will slide back farther if you don't fix it now. Again you looked down at the third fence. Over the fence you pinched with you're knee and you're leg slid back. Also when you feel comfortable jumping, try not to use you're horses kneck as support.
Eight Video: I am only going to critique the first course.
Nineth Video: same
Elleventh Video: I can't really critique the video from the front.
Over all you have things you need to work on. You and you're horse look like a great pair for only jumping 8 months. Have Fun!!
