I agree with everyone else here. You do look very long in that picture. Right about an inch or better judging by that. But its what you feel most comfortable shooting and are most consistant with. Keep in mind that usually, if you have to make a drastic change in your length from what you are used to, or in your anchor, it may feel weird at first. But eventually you will feel just as comfortable or even more comfy in that spot.

I personally shoot an honest 29" draw, but am more consistant with it at 28.5. Its only a 1/2, but it makes a big difference for me.
