One thing I noticed in your video, and I can't say for sure how much correcting it will help accuracy (but still), is that you draw the bow all the way back, then collapse a slight bit just before you release. Watch the tip of your arrow.
In one motion you draw all the way back, only the very tip of the arrow is visible. You adjust your anchor slightly, it looks like you're doing it by bringing your face down to the arrow, and while you do that more of the arrow becomes visible past the bow. It's maybe a half-inch to an inch, but what this shows it that you are losing back tension, even if just for a brief moment. You seem to be doing this on every single shot.
This is a lesson that all archers can take from Olympic-style target archers. They often use a very slow draw and a clicker to tell them exactly when to release. They make sure their draw is one continuous motion and that they never lose or reduce back tension.
I've struggled with this in the past. In fact, I still catch myself doing it sometimes, but it's getting better.
So to correct it, try to draw directly to anchor. Don't draw back then adjust. Don't lose or reduce back tension at any time. If you can hold it constant or continue to increase it slightly, that might work. But it's better to just draw straight to anchor and then release. Perhaps a very short hold. I find that the easiest way to do this is to draw more slowly and to make sure I come back straight to anchor.
When I teach new archers, one of the things I find myself telling them often is Draw the string to your face; don't bring your face to the string. This is a different way of saying the same thing. A lot of people have the natural tendency to draw back however it feels natural, and then to move their face or to crane their neck forward to get to "anchor." They could fix that by just drawing straight to the anchor they use -- or by switching to a different anchoring point that matches their natural draw.
Other than that, which jumped out to me, nothing else looks too bad. I think if you could correct that though you'd end up with a more consistent draw and release, and hopefully you'd have improved accuracy and precision to go with it. Personally, often when I find myself making bad shots I'm either short-drawing or collapsing or flubbing my release. And often when the release is bad it's because I collapsed/lost tension for a moment.
EDIT: It also looks like you are starting your draw from this hunched/leaned forward position, then opening back up, then leaning your neck forward again. You might have better luck if you start from an open position, stay in that position while you draw to anchor, and then remain in that position while you release. It's not extreme, but it's noticeable.
