A bedroom theme idea? Opinions, on what you think?

Right now my room is green (it was green when we moved in), and has posters and colors all over. Right now I'm not really into all of it, so I want to change my room. I'm going for the artsy type room. White, black, brown, tan, and a dark yellow. Pictures of art all over, my books, floral flowers, and things related to that. Any opinions? Ideas? Picture would really be helpful! Thanks so much!
