No, you do not need to be classically beautiful to be accepted.
We only run tests on your image to ensure your face is not too generic. In rare cases, some faces cannot be used because they are too similar to others already in our system. This is uncommon, and roughly 9 out of 10 submissions are accepted.
You do not need to look a certain way. We will enhance and refine your image so you look beautiful, and you will be very happy with the results.
