What Terry said, but what I see in your follow thru is that it's long and flowing, but most of it is just a conscious movement on your part and not a reaction to your shot.....when you release the string,your hand doesn't fly back as a reaction to you using you back tension and a positive push/pull. It just kinda falls,then you move it back after it's made it's natural reaction,or lack there of, to the shot.By clicking start/pause you'll see what I mean.
By doing what Terry said about bringing the string to your face and not the other way around will help.
But you're getting static at anchor to the point of a slight collapse as you release. If you need to hold that long(probably don't), you need to keep pulling back ever so slightly as you do so.....
