Ok, a couple things. 1st hold your bow as straight up-and-down as possible. The bow should be at 90 degrees to the floor. Your bow arm should be parallel to the floor. 2nd, make sure that you're grabbing the string in the correct "arrow nocked" position. On the picture about the one I'm posting it looks like you're holding the string about 1 1/2 lower than where the arrow would actually be nocked on the string. I suggest you use and arrow to get your reference point. Nock the arrow on the string with the bow braces. The string and the arrow should be a 90 degree angle. Of course the arrow shaft should be on your hand or the arrow rest.
It looks like you have hinge starting on the top limb. Here's a picture of my suggestions.
