Is there a ground pole on the other side of the first jump? If not - You shouldn't jump it the other way. If there is a ground pole it should always be on the front of the jump.
He looks like a lovely, honest little horse.
In between the two jumps you are ver insecure in your saddle - You need to sink back into the saddle, sit up straight, pick up contact, and support and actually ride him between the jumps. especially if he is a green jumper - He needs your help to bring himself together and judge that distance. He got the wrong stride on the last one because you just let him run through - He needs to sit up, come back, and you need to ride himj to the base of the jump.
Can't really see much else due to the quality of the video.
