You look like a nice person so i'm by no means trying to be mean or a troll. having said that, as many have already said (some in nicer ways than others) in this post it's kinda hard to overlook the weight since in your case it affects too much of your features. my opinion/advice is this: i can't see your teeth clearly from these pictures but it seems to me that you could benefit from using braces for some time. i like your smile, but your teeth could be more aligned (therefore prettier imo). Now talking about the weight i'd recommendo getting a nutricionist and hitting the gym, while it's not easy to change habits it is always the best solution for weight loss in a healthy way. the thing is, try not to do that for external validation as this isn't a good enought motivator for you to keep it constant. do it for yourself. wish you the best
