Ok what to do with my room?

So i get to re-do my room. I am 16 years old. I want it to be mature but something that resembles my personality. The carpet is purple, that i can not change, i also have all my furniture. Which is white, and can really fit with any style. I can repaint my walls, and take down my bunny wall paper(finally) and what ever else i want. I want to somehow do like a baton twirling/ dancing room. Somehow combine it with my design. I have been a baton twirler since 5 and a dancer since 4 (mainly ballet, but i do it all). So any cool ideas to do with my room? Thanks.
