Re: critique my form (update with better quality)
A few minor things, other than the slight sky-draw which has already been mentioned. First, your snatching the trigger. If your release is adjustable, and most are, shorten it by half of what it is that way the trigger is deeper in your finger and off of your finger tip, and then practice squeezing the trigger instead of punching it�having it deeper will make it harder to punch the trigger. Having it further back also makes it easier to engage your upper back muscles and make it go off, similar to back tension. Secondly, get a wrist sling. You are slightly snatching the bow as soon as you release the arrow, which will or can cause some torque issues. Potentially down the road, combined with punching that trigger it could setup numerous other problems relating to anticipating the shot. With a wrist sling you can completely eliminate the need for your hand to grab the bow�that is what the sling is there for (do not put it tight on your wrist either). You can order a custom color in various designs from numerous places for $10-$15 dollars. Some guys don't use slings, but I recommend them to everyone I work with because snatching the bow, and the results of doing so is one of the biggest flaws I see�nothing like the fear of dropping $1000 piece of gear on the ground.
All in all everything looks good, just a few minor things�you're well on your way! :)
