I’m 17 and ive always loved the new age contemporary type style of rooms. So my dads adding onto our house and i’m getting a new room and i’ve come up with pretty much all of the design, i just want to know what are some good colors to add. i want to go with the red black white grey theme. (here’s what i have so far–http://i26.tinypic.com/30ac6eo.jpg).

does anyone have any other suggestions to the wall murral at the far end of the room? i’m into like vintage, hippie’sh , urban, random stuff.. so i dont know. just let me know any input you have on anything like the colors, furniture, and if i dont end up getting the hanging ball chair what should i put instead? ( i probably wont because the cheapest is like 600$)

p.s. im getting a light grey shag rug(for those that want to visualize ha)

Thanks ahead of time
