Everyone hunts for different reasons. I get it, misses are no fun. You have gotten great advice on how to improve your shooting, on a technical level, and how to improve your mental preparation before the shot. These tips will help you to harvest game for sure.
I think the real question is why do you hunt with trad gear? What is motivating you to go all traditional? You said, "I hunt to harvest game, that's kind of the point." I know what you mean. In a strict interpretation of what we're doing, we all hunt to harvest game. On a personal level, I hunt with trad gear because I couldn't care less about the need to harvest game. I enjoy my time afield and for me, that's enough. As for me, I feel it's more gratifying to kill game with my longbow or not at all with a compound. Having said that, I haven't killed a deer since 2009. I think if you explore your true desires about what is driving your conversion to trad, you'll find the best course for you, be it trad or compound. In the end, you need to find fulfillment in whatever method you use.
Best regards,
