Nice bow. I'm no archery coach, but I'll give it a try....

For starters, it LOOKS like your DL is too long, but that might just be due to the fact that your left shoulder is bunched up. Try lowering your left shoulder and pushing your bow arm out just a tad. With your shoulder bunched up like that, it would be really tough to squeeze your shoulder blades together and properly pull through the shot with back tension.

I'd also shorten up that release buckle if you can. By fixing your bunched shoulder and shortening your release, you can get that release hand into a better position. Right now it looks like your release hand is too far back - almost behind your head. Having a draw length too long can make your bow feel10 lbs heavier than it is.

Also, can you take another pic that shows your entire right arm?
