Stability is the key. Make sure that when you position yourself for a shot, that you feel stable and secure. If you are fighting gravity or engaging your abs to try to steady yourself, you will tense up. Another thing that I find helps greatly is to have someone record your shooting. This way you can decipher if you’re dropping your lead arm, or leaning out to much. Shaking ect…. Watching videos of you shooting, can help you recognize what you are doing different or incorrect. And finally a lot of guys coming over from the tree stand world, do better if they look straight ahead and draw their bow at the horizon, then pivot at the waist to take your shot. It helps with t form, until you get more used to rolling your rope through your carabiner and then drawing. Hope this helps
