It's normal. I'm a 9 on the face, yet in pictures I look like shit. It's because we aren't used to seeing every little imperfection we have, and when we look at the non reversed picture, it brings them out.
If you want to see this effect in real time, put two mirrors next to each other, and put them at an angle so you can see yourself as how others see you.
