BigRich315:
Our local License Office will retake a picture but only if the subject has their eyes closed or if they sneeze or something that results in a photo that does not really look like the person. A do-over to get a better angle is something they won't do.
Now, I have a suggestion. Before you get your photo taken, ask the agent at the desk if they will do retakes. A polite question with a little humor might help your case. Our License Offices are privately run and the people who work there are, in my experience, pretty nice.
The worst they can say is "no".
