Hey ^^ I would paint the walls blue or green, add white furniture, blue or green bedding and stuff to create texture and patterns on the walls and maybe even on the flor (maybe a green rug). Hanging plants would also be nice and lava lamps would be perfect light sources. Maybe you also have an aquarium you can install in your room but that wouldn't be necessary. An iPod-mirror would also look sooo good but they are way to expensive - I would still look for something that gives off the same vibe but is affordable. I hope this is a good inspiration and can help you to transform your room. You could also search for room-examples on Pinterest or just google it. or you can make a vision board. :D
