As always......hard to tell from one pic. Doesn't look bad?

One thing I do notice.....don't grip your release. Your trigger finger position looks OK, but your release hand fingers should hang naturally, triggering your release. If you Grip your release body, then you cannot fire the shot with back tension, all that is moving is your index finger. Unless you have superhuman squeezing ability and the capability of disconnecting your brain from it you will anticipate the shot. Anticipation leads to punching which leads to inconsistent accuracy.
The most common case of flyers IMO.
Back tension = consistent accuracy with whatever form you decide works for you.
