Another thing about the elbow bend. bend it just enought so your elbow isnot locked and bend it OUTWARD not down, that way you will avoid forearm SLAP. PS good so see another lefty here. I do everything else right handed but shoot a gun, bow, and pool lefty.

Yep, get that string off your face and on the tip of your nose. I don't know if you are quit an inch short, but that it one thing I would definitely say do.
