PRACTICE PRACTICE PRACTICE!! It could be a number of things and many people shoot many different ways. In my opinion you need to find what if comfortable and consistent for you. For an anchor point example the hand that I pull back with a place my thumb behind my neck for a solid anchor. Also, just relax, do not release the arrow until you are ready this can sometimes cause target panic in some situations. Also if you have a level on the site of your bow, use it! torquing your bow could cause inconsistence and frustration. Also do not shoot until your arms are numb. The more tired you get the more inconsistant you are going to shoot and just get frustrated. Shoot 5 or 6 times and take a rest. I hope some of this helps.
