Michael, Ok, first we've got to get you nocking the arrow safely...doing it the way you are with a broadhead is downright dangerous :eek: Most nock an arrow by holding the nock or the arrow very close to the feathers, laying the arrow on the rest first, then connecting to string...far safer than waving a razor sharp broadhead around your head. I know it sounds like a little thing but that was the first thing I noticed.
In the first video, I think your drawing arm looks in good alignment. You have a minor "pluck" but I'll bet it doesn't effect your shot much because of the good elbow alignment. It might be a minor problem, easily remedied by more back tension...the drawing hand would come straight back on release instead of away from the face.
It looks like the shoulder of your bow arm might be slightly out of alignment...pointed a tad more to your left. Try closing up your stance a little (turn more of your side to the target) to get your bow shoulder more in alignment.
In both the 1st and 2nd video I can see your head come down to your anchor instead of the anchor coming to your head. I think most people shoot better if their head stays static and the rest of their form moves to accomodate it during the shot process.
In the second video it looks like you are dropping your bow arm pretty quickly. Follow through, even exaggerated slightly, is very beneficial to accuracy. You also look like you are leaning a good bit forward into the shot (your front bow shoulder is lower than your rear draw shoulder). I shoot like this too and find it very comfortable, but be aware it does shorten your draw length. Better alignment in a more defined "T" might prove more accurate for you, something to try. You would then bend only at the waist for shots above/below that level. Again, I shoot like this too and it works for me, but thought I should point it out at least.
Again, drawing arm/elbow alignment look in great alignment to me, that's a tough one for a lot of us.
Hope this helps, your mileage may vary, good luck!
