I would agree with Paul that it is hard to be sure from that angle. Most experts say the arrow nock should be directly under the eye when at full draw. Looking at that, it seems like the nock is slighty behind your eye, meaning the draw may be slightly long. Then again, your knuckle of the index finger seems to be right behind the jaw bone where you should be anchoring. You are also not displaying any clear signs of drawing too long - leaning back, draw elbow below the draw hand, etc. If it were me, I would just straighten out the bow arm elbow, but some really like to shoot with a slightly bent arm. Maybe you should have more pics taken, or visit a local pro shop for more feedback.
I place my draw hand up against my jaw between the 2nd and 3rd knuckle. I'm actually not behind my jawbone, but at that back "notch" of my mandible. The guy at the proshop watched me shoot before I left his shop. He said that he could not detect any problems with the longer draw. Still, we agreed that I should shoot the bow over the weekend to make sure.
