Sounds like a great idea, the colors are a bit on the bright side for me but I guess that is forgiven, I am a guy. I am into DIY staff and I am impressed you want to tackle this on your own. Do you have all the tools you may need. There is a great online store where I get most of my equipment, visit http://www.caulfieldindustrial.com and get lots of options.
Good luck on your venture. It is your room, be as creative as you want-you are going to live in it so do as you please, just be safe.
