Yeah the draw is too short, and that is causing your bow arm to be bent too much. Your bow arm should have a slight bend, not too much or not locked. When you lengthen your draw that should bring the elbow of your draw arm down. Your elbow should be pointing directly behind you, not up in the air like in the picture. Your form should look like the letter "T". With your draw arm and bow arm directly in line with one another.
