Looks pretty good Gus. The video is a little jerky on my browser, but I don't see much glaring error. It looks like you have decent shoulder alignment and consistent follow through. I'd like to see you take a little more time at anchor and expand through the follow through. I see a slight collapse after you reach anchor. Try to make sure your shoulders aren't coming forward during the end of the shot. Keep that chest out in front, keep expanding, don't let it collapse.
One more thing that I noticed was that you seem to have a death grip on the riser handle. Without being there to watch you shoot and study your groups, it's hard to comment. Ordinarily, do you have any right/left error?
