Draw length is fine if you straighten your bow arm up, which also tells me you probably draw across your chest. Nothing falls into alignment when you do that.
A good indicator is if your bicep on your release arm gets tired as you practice. With good form your bow arm will tire long before the release arm as you should be using almost no muscles in your release arm to draw and hold your bow at full draw until you release it.wapitibob, could you clarify what "drawing across the chest means"? I'm 100% self taught but I've been shooting since I was 4 years old, and think I have pretty decent form, but I'm not sure what exactly that means.
