Take any portrait, mirror the left half onto itself, then mirror the right. You get two faces, both symmetrical, both subtly wrong. Almost nobody prefers either to the original.
Symmetry correlates with attractiveness ratings, but weakly, and it saturates fast — past a modest threshold, extra symmetry stops adding anything and starts reading as uncanny.
What actually drives 'striking' ratings in aesthetic models is contrast: the distance between features, the definition at the jaw and cheekbone, and the clarity of the outline. Distinctive beats even, consistently.
This is good news. Your asymmetries are the part of your face that people actually recognise you by.
