How should I change my room around?

I want to move my Queen size bed, my dresser, my HUGE desk, my TV, and my nightstand somewhere else in my room. I am a 13 years old. Right now my North and South walls are a purple Lilac color and my east and west walls are a greenish blue teal color. On the north wall I have my dresser there, on my south wall I have my small closet and my night stand because it doesnt fit on the east wall by my bed, and on my west wall I have my window, TV and my HUMONGOUS desk!!! Thanks :)
