What do I need to have a career in ballet?

I have super long legs and a short torso. I am skinny... like bony. YOu can see my sternum bones and colar bone and all my ribs and my hip bones through my leo... i'm just naturally like this. I'm flat chested. I weigh 114 and I'm 5'7.5 but i'm done growing. My legs are muscular but lean muscle. I'm naturally flexible. I've had every split my entire life. I want to get a straight up and down arebesque and I'm not there yet... i can do it assissted though. In dance 4 other girls and i were all comparing our bodies and they all determined i look the most like a ballet dancer... I just want to achieve all the potential I have. I have amazing arches according to my teacher and my nickname is "Gumby" like that flexible cartoon character or something. What things should I do to become a ballerina. I've danced for 13 years and I'm 15. I am on the highest level at my competitive studio and I also do alacarte classes at a professional ballet studio twice a week for extra pointe. What do I need to do?
