Room Decor?

Alright, so my bedroom is pink and white. I have a pink white and light brown roxy bed spread and pink and white curtians and the whole nine yards but im missing something. My walls are so boring and bare! I think im going to be painting them pale pink like just a color with a little tint of pink not really something that STICKS OUT! So does anyone have any ideas of what i could put on my walls like pictures or anything! Im a teenager so nothing like granny-ish. Thanks!
