Do you always shoot with your body at a 45 degree angle to the target? You don't look all that comfortable... shoulder and arms seem like they are at odd angles.

I can't tell from this angle very well... it could be the poor lighting or the cell phone quality shot... but it looks like your right elbow is stuck out and not in a direct line with your arrow... if your elbow and forearms were hollow and I stood behind you... I should be able to see down your elbow and to the target like I was looking down a rifle barrel.
