I would wager that you have high levels of facial symmetry. Technically. everyone is asymmetrical but the people with the least amount of noticeable asymmetries tend to be viewed as more attractive. However, symmetry, by itself, isn't an indicator of attractiveness. One can look bland without enough color contrast and/or at least one stand out feature.
