I'm a tad bit self conscious about my body?

I'm 16, 5' 3" and slender. I'm thin and have no fat on this body I actually am very toned because I'm a gymnast. The thing is I don't have much of a chest and I have a bubble haha (sticks out but it's not wide) I have curves I'm not just a bean pole but still I've always wanted thicker legs and a bigger chest. Does my body sound unappealing?
