I did a quick look at the witch, it's very hard to find a good photo of her looking straight with a neutral expression for proper analysis. She also is constantly covered in make-up and styling to cover any imperfections.
That said, she is definitely not perfectly symmetrical. Many times asymmetric features become obvious when you change your perspective, and view the face from below, or at an odd angle. This image just quickly points out some common features.
The bone and muscle anatomy is so precise and minute, that any change in growth or mutation can lead to pretty drastic facial feature abnormalities. But again, I don't think this can be interpreted as clear signs of deviancy.
