^Very good. imo the bow arm and the high anchor point are your biggest probs. and imo the arent major as long as your consistent. the thing about changing anchor is it could result in tuning and resighting the bow. you might want to wait until season is over bfore you dicide to change everything jmo. but if the high anchor works well and you think that you are getting good results than by all means stick with it. it doesnt have to be a certain way, but changing some little stuff might make you better.
btw, its great you strive to be ethical and one shot one kill oriented. that is all of our goals, as im sure you know but i would like to say, bow hunting is a totally different world. there is so much more to it than hitting them with a bullet projected at thousands of fps. even the best of us lose deer and understand it can and probably will happen again. if it does happen to you, just try to not get too down on yourself. dont let it ruin your season. you obviously strive to be the best you can and at least you will know that you did everythhing in your power to be ethical. that beingsaid i know you know this and im not tryin to preachbut sometimes its good to hear stuff from others.
good luck
