If I may jump in....The 1st thing I see is you may want to shorten the drawlength a little,you are leaning back at the waist a good bit and IMHO your anchor point is kinda far back.By shortening up it will help your anchor as well as put your head in the erect position(your head is tilted down)The idea is your body and arms should form a "T" with your head erect.I don't think your draw is excessivly long but may need shortened a tad and don't lean back at the waist.
I see your hand is closed which is OK if your hand is closed but relaxed and not GRIPPING the bow.
I can't see your feet,but it looks like your stance is closed pretty tight,you may want to open up a shade and see if it feels any better.
