What are some good idea's for a emo/scene bedroom?

I’m 15. And right now my bedroom is black and a dark pink(2 walls are black and 2 are pink). It’s been that way for a long time now and I’m getting tired of it. I love the emo/scene look. I can repaint the walls any color that I want. I was thinking maybe painting the walls black and white.and maybe use some other bright colors in like rugs or lamps etc. I want a lot of band posters to cover one of the walls but I don’t have much money to spend in buying them:( and the cheaper ones at Hot Topic are not that great and they don’t have much to choose from. I love neon colors but after looking at that pink for such a long time I don’t really want those colors on my wall.My carpet is this horrid brown color and I can’t change it:( So I’m thinking of maybe just getting a rug that will cover my whole floor. I don’t really have any idea’s besides those,so I need more idea’s..can you give me some? I don’t want my room to be girly looking. My room is a pretty good size its not small at all. but I have a queen size bed which takes up a pretty good amount of space. (the bed is white). This is some on the stuff I already have -A black book case -A black dresser -lots of photos of friends and family -pink rugs -A few posters and also I absolutely LOVE photography and I want to somehow bring that into my room also. Any ideas you guys have will be extremely helpful. :)
Thanks:)
