I'm decorating my room...does anyone have ideas?

My bedspread is going to be either orange with teal, pink, and brown stripes or teal with orange, blue, pink, and turqoise stripes. My ceiling is really awesome, with stars and a moon painted on it (glow-in-the-dark) and some clouds painted, too. (these aren't glow-in-the-dark) My carpet is dark purple, but I might recarpet it. Also, should I hang up really cool teal Japanese paper lanterns? Or is that way too weird?
