Short drawing, proper draw length and over drawing CAN be a pretty fine line. Many self taught folks tend to draw clear back along their cheek or even to near the ear. This puts the arrow nock and bow string off to the right for a right handed shooter and you will always have to have a "hold off" to the right of the target.
Some can shoot well this way but I feel that it adds complication to the shot.
I do not know if you wear glasses or not but even using sunglasses, the string should be in front of and even touching the glasses lens and not back along the temple bow of the glasses.
If you can, find an instructor there at the home of aviation. That is always the shortest route to a correction like this.
