Mike,
That is looking REALLY GOOD!! You might consider bottling it and selling it.
Your bow arm is just a LITTLE off square with your spine and I THINK that is why your bow arm recoils down on release, BUT, I'm REALLY nit picking here. I don't think I'd change anything if I were you! And especially if you are happy with your shooting.
I also believe that you are at a point where this kind of video analysis won't help much more. I think further progress ( if any) will need to be in person. That's where coaches can help interactively rather than just visually.
Good stuff!!
Arne
