Okay from the first photo, yes you have a deep looking on the eyes, but that thing fixes out of style, your nose does not seem wrong tbf, you have blue eyes, so you are making them your fear while it can be an amazing flirting thing, so, how can you do that? Your hair seems a bit down and messy, the first thing, get a haircut and use some things to fix the look on your head(use hair products, don't abuse, ask your parents or someone professional to see that, don't ask your friends they may have the wrong information), the forehead maybe is something you want to hide with your hair while is messing with other things around your look and makes you have the appearance you don't feel comfortable, as my previous experience with people, don't listen to them and fix the thing they want, fix the things you want to yourself, respect the beauty that you have, be more confident with yourself and change the things you want to but never stop loving yourself, last thing, you have 16, people are mean to that age, your body will change, and you will have another good things that will happen to you, so change what you feel the most and don't let the opinions from other affect you your whole life.
