Skyou,
I want you and everybody who focuses on they're right arm connection to listen to this; Focus on keep your upper left side connected and the right will automatically do what it should do. Forcing the right arm close to the body causes problems with your release and a too flat swing plane. Next time you go to the range try this: At address, assuming you're a righty, feel that your upper left arm is connected to your outer left pec (chest) and then turn your body back and through while feeling this connection with your upper left side. Your swing will feel shorter and tighter so start with a short iron and make 3/4 swings. When you get your arms and body swinging together correctly you will feel effortless power and more consistency with your shots. Also, notice how your right arm automatically moves correctly. Let me know if that works.
