I did watch the whole video, and admire your form. 99% of what I see is good, which I would expect, given your training, but I don't suppose that's why you posted it here.
I think you can work on simplifying your draw and anchor. I see you drawing the bow in one motion, and then locating your nose anchor in another motion. As a result, sometimes you have to move your head back to get your nose anchor, and other times I see you losing a bit of back tension and letting your string hand creep forward just a tad. Then after all that is done, I see you stabilize yourself for a couple of seconds, during which time you probably regain whatever back tension you might have lost, and because of that you can then get off what is probably a pretty good shot.
What you might consider doing is to move your head into position as you draw the bow, so your nose is in position to meet the cock feather as you reach full draw. Then continue to build back tension until the conclusion of your shot. It is not all that easy using Rick's method of anchoring to continue to build back tension as you hold, since the cock feather is already touching your nose when you start your hold, but it is possible, since the arrow doesn't have to move back much, if any, further as you build back tension at full draw.
It is possible that you may be cramping yourself a bit, and may need to move the cock feather a little further down the arrow (isn't it fun to think of refletching all your arrows?). I say that because it seems like when you naturally draw the arrow to full draw, you then have to move your head back a little to get your nose behind the cock feather. Ideally, holding your head in a naturally upright position, you should be able to reach full draw at the exact same time that the back of the cock feather barely touches your nose, allowing for a slight additional backwards movement of the arrow as you continue to build back tension without jamming the cock feather into your nose.
