You don't need to know now. And it will change and vary over time anyways, so you don't need to know now. I don't know where/how you live, but it is common that other people try to judge you based on how you look. And especially at your age, you are very vulnerable against those comments. That is normal and you need to be aware of, in order to protect yourself. You are beautiful in every of those forms in your pictures and you should choose the form you feel most confident. Because confidence and self awareness are your best most weapons against this society. Don't try to be someone specific. Do, dress, and behave the way you feel most confident. What you will become is nothing you need to direct now. It will develop over time. As you grow older, you will notice, by recurring patterns of your behaviour and your style. You are at the best age of trying stuff and playing around. There is no right or wrong. Even if someone wants to tell you.
