I'm guessing you average about the same as me - a high sub-200.
Your footwork and swing look consistent and good to me, especially on the back-swing. The only thing I can say is that if you were to lean just a smidge to the right, the ball would swing under your nose, making it easier to aim. As it is, you seem to swing it out coming down from the backswing - sometimes and sometimes not, meaning that while the rest of your approach is the same, the final release is different, and so the ball goes to the right. Then sometimes you try to correct for that by putting more fingers (lift) on the ball, and it goes too far left.
