RedLipsI'm a girl and I think you're very pretty
Sure I can see what is annoying about your chin. Maybe you should see that with a surgeon. Although as many people said here, you're fine the way you are.
People say that you look how you feel. If you feel gorgeous you will be seen as gorgeous by others. If you feel ugly, maybe people won't find you ugly but they will think "she's average".
I have a fried who has very visible gum (same size as her teeth, which are short by the way) and she acts like she's so pretty (and probably thinks she is and she doesn't seem to be bothered about her teeth). Well, she gets so much attention from guys!
