Ombre Curtains

Ok, so I like butterflies and thought it would be a cold room design idea. So I try to keep from being little kiddish bc I am a teenager so let me know if these ideas seem too young. I have all the furniture in stainless steel and maple, and I will use this bed linen:

I'll paint the walls the green butterflies described. Then, through a wall up, I'll write "I will stretch my wings and I'll learn to fly" the baby blue. I will have with the white curtains blinds: http://www.target.com/WINDOW- SHEER-XHIL-...
Then I'll make a indoor fountain using this: http://www.target.com/Flamed-Butterfly-F ... and I did not pot a photo. So what do you think?

You have a very pleasant taste.
Just keep the walls and floors a nice neutral color.
