I'd have to say that being ugly or pretty is a very opinionated thing. In my opinion, I think that people are dramatic over how they feel about themselves. There might be features people find interesting more than others since by now things are being re-used like certain facial features and a lot of people find them attractive due to their own opinions. I think in the end, you not liking your looks is just you being interested in other features that you feel you don't have and thus thinking you are ugly. I, myself, have an oval-like face that I don't really like since I like more of a smaller face. But to some, they like it. It's all opinions! =D
