Overall, I am very happy with my appearance. When I was a little kid, I thought I was ugly, but by high school, I felt the opposite. I had grown taller than most of my friends, and I started getting a lot more attention from girls, so I got a lot more confident about my looks in high school. I also used to be extremely scrawny, but once I started playing sports, my frame filled out substantially.
For my face specifically, I am also very pleased. I think my proportions are good, and I have good features. I like my eyes, my nose, my brow, my cheeks, and the overall structure. There are also a couple small things that I don't like. I still get acne sometimes, and I have a few pock marks from past acne. I could stand to have a more "angular" jawline. And finally, I wish I could grow a beard.
But for the most part I'm not insecure about my appearance at all. I like what I see in the mirror, and I almost never feel really bad about my face. I know I'm not quite as good looking as a top male model, but I'd rather be strong and masculine than a super good looking prettyboy.
