Can I be really good at ballet ?

I didn't put this in my other answer, but i was in ballet for 2 years when i was in 1st and 2nd grade. Then i stopped and joined gymnastics for 2 years. Then i stopped again and i did pilates for awhile. Now I'm on track and i want to know if i can join ballet still since i had previous experience. I'm 14 almost 15 what do you think? (i weigh 110lb)
