What do you guys think about this idea for my room? (Teenage Girl Bedroom design Idea!:D)?

So I've been thinking for a while now that I wanted to update my room and make it more chic and classy. I watched this http://www.youtube.com/watch?v=9n5xalbGSVk today and if you watch the first few seconds of the clip, you'll notice a kind of face silhouette with long eyelashes and I really think its very cute! I asked my Mom if I could do this and she agreed so I'm planning on getting that started in the holidays. As well as a chic look, I'd want a kind of boutique-esque kind of feel? So how could I do this? Colour schemes,Decor,Accesories etc..? I also had my own idea of downloading or buying some lettering templates and then across one of my walls, have a fashion quote or something? Like one of Coco Chanel's :D Please guys, tell me if you like my ideas and give me some more advice! Thanks :') <33
