I noticed a couple things. First, in the rear view, you have a lot of head movement. Too much for my liking.
Second, your starting stance is good with knees slightly bent and a slight bend forward at the waist. I consider this a good athletic stance. But then, as you go into your knee lift, you stand up straight. And when you go into your stride, your back leg collapses and causes a posture shift toward 2B. The result of the posture shift is that your weight shifts toward 2B as well and that prevents you from getting out over your front leg as you should. The end result - as you can see in the side view - is that you fall off to the side and even a bit backward after you release the ball.
My suggestion is to not stand up straight into your knee lift. Try to lead with the front hip into foot plant but don’t let head and shoulders lean back toward 2B (i.e. eliminate the big posture change). Doing these things may also cut down on all of that head movement.
