Bow hand isn't relaxed enough, and your bow arm is bent too much. Your draw elbow is a little high, but I think if you straighten out your bow arm, that would be rectified.
If you would/could,straighten out your bow arm to almost completely straight,right before the elbow locks but make sure it is relaxed and relax your fingers a bit and repost a picture for comparison.Do it from the exact same view and maybe even the same shirt. I don't know if the draw length will allow (looks really short to me)it but try it.There is something I want to see,and maybe point out.
Where can a guy get one of those sleeveless shirts ?? I have a fetish ya know,,and as a plus its a bow techie shirt
