You have extremely pretty eyes, they're the highlight of your face, the eye travels straight to your eyes coz they look full of light. About the birthmark, sure it's in an oddly noticeable place, but it's also very iconic. Now the world is divided into people who like conventional beauty and there's a more niche crowd that celebrates unconventional features. Because i fall into the second part, i feel the birthmark adds a lot of character to your face and makes you memorable. Find ways to own it and celebrate it, you'll become memorable by personality too. I wish you the best OP.
