okay, my room is going to be blue and brown and kinda green in places but thats kinda the whole theme and im 15 years old so i want a mature room. REALLY!!! and my bathroom, im thinking yellow walls and brown bathroom stuff like a brown shower curtain. would that look okay. but in my bdroom, im thinking two walls blue and the opposite two walls brown, dark brown and dark blue. also, like 4 blue and green round paper lanterns, a brown bean bag, a cork shelf thing to go on your walls, to put like picture frames on its really cool, and a magazine rack to go on my wall, its pretty small size, 3 slots in it. well i really need to know if this sounds mature and if not please give me some websites where i can go and look or put your bedroom picture on here cause i really need help!!! thanks~
