Try to focus more on holding the bow at full draw, rather than focusing on releasing! You WILL sometimes need to hold the bow drawn for a bit waiting for a shot! Strap on your release. Next, draw the bow and settle in for 20 seconds. Now try that with fingers. Which one is more comfortable? If you start shaking then you either need to practice more or have your draw weight lowered. Deer will see you shaking. Seeing deer will make you shake more. Being cold in the stand will make you shake more. Remember, the first shot at a deer is the only one that counts and it can happen quick. Make it count. I usually loose 10-12 arrows daily. Good luck! Keep practicing.
