Deadbolt, I agree with Terry, bet if you get the drawing elbow down it will help quite a bit with the release etc.
I also noticed you anchor, then draw slightly further before you release. Now, it might work...but I'll bet it's hard to get consistent unless you are using some sort of secondary anchor for the last part of the shot...like you anchor at the corner of your mouth at first then pull until you touch your canine tooth. Usually that "stop/start" causes some problems in most folks. Most find it easier to either pull all the way through while releasing at some anchor point (without really "stopping" for an appreciable length of time) or stop at anchor point and release from there...not creeping in any direction from that original point. May not be a problem for you but something to think about.
JBiorn, I would think that's indicative of a slight misalingment...It looks to me from the overhead that your bow shoulder is pointing slightly left of the target...causing lefty fliers when you release because your shoulder is having to pull the bow on target to the left instead of a straight ahead push if it were more lined up. Could be the angle though, can't tell for sure.
Good luck.
