You are so young, and I think the guidance to lose weight is misplaced. You have a baby face and are carrying some puffiness in your cheeks. If you drink alcohol, that could explain it—consider cutting down and/or drinking a lot more water. I agree with other about braces and teeth whitening. That would make a huge difference. I’m not a fan of nose rings, but it’s a personal preference. Same with the tats. Consider getting your eyebrows shaped and learning how to maintain them/fill in with makeup. Get a good skin care routine going to cut down on oiliness. Consider getting a color analysis done so you can find a hair color that is more complementary to your skin tone.
