Yes, under your eye!!!! You might try this: put a vertical strip of blue masking tape on your target all the way top to bottom. Now, when you reach full draw, if your arrow nock is under your eye, it will look as though the arrow and tape form one line. If you are anchoring off to the side of your face, you will see the arrow point on the tape but will be able to see the shaft coming in to the tape from your left. I believe that this is the biggest cause of you shooting to the right.
Your arrows are probably too stiff and especially with only 100 grain points, which may add to the offset. If you have any, try 145 or 160 grain points BUT do not obsess on this yet. First step is to be sure your string hand is in tight on your face and the arrow nock is under your eye.
