Ok the video confirmed a lot of what I, and a few other people said about the pictures. You are throwing across your body by almost a foot. That is cutting off your hips. As, xv84 said in the other thread, your front leg is much too stiff. Also you are getting no drag at all from the back foot. Maybe someone who is more schooled in NPA jargon could explain the back foot drag. Also, your follow through is way too abrupt. That is just asking for elbow and shoulder problems. You need to try and get some semblance of foward lean. Try and get your chest out over your front knee, so that you can complete your follow through and allow the larger muscles in your upper back and lat slow your arm down rather than forcing your arm to stop.
My suggestion as far as something to work on though is your stride. First work on landing with your front foot perpendicular to your back foot. Then, work to lengthen that stride. I think those corrections would fix a lot of the other problems which i think are caused by your stride.
