How can I recreate this mature Paris bedroom into a trendy teen room? - mature jpg

I'm 13 and have a beach theme at the moment, it became a little less for my style and taste.
My furniture, which is the fourth would be in French, made me think about a topic of Paris equivalent.

I like this part: http://www.swell-group.co.uk/town/paris/img/paris_bedroom.jpg

How can it anew in a reasonable age (not yet fully developed) in a room with a little more color?

Thank you!
