Shoot your bow standing, kneeling, sitting, behind a tree where you have to lean around it to see your target. Anything you can do after you have developed a great shooting form with a bow will help you in the field. Too many guys stand at perfect form shooting a bow then when in the field between the excitement and the terrain situation they lose concentration of form and the shot misses. Test yourself hundreds of ways to see how your form reacts to your shooting situation. Take your target to your deer stand and shoot from your tree at different ranges and situations, in the off season of course. Concentrating on form is half the battle when shooting at live game, the other half is controlling situation (waiting for the right position of the animal, knowing range, and controlling your nerves). It's not always easy to do. If you want not miss as much and try not to wound animals wait for the shot and not try to make it happen anyway.

The most important thing to do when shooting animals with a bow is to pick a spot on that animal and aim at it. Don't just get a animal inside your sight ring and let er fly. That one thing has made me a better hunting shot than anything else. Good luck.
