RE: hows my form (theres a surprise in this thread)
Watch yourself in a mirror and try to keep your shoulders over your feet while keeping you hips inline as well.I can't tell if you are leaning back or you just have your hips pushed forward.
Get an arrow on that string so you don't accidently dry fire the bow.
AND,good catch by bigbulls,that tube is way too short.
Your release might be a tad too long as well.
