After tracing I went on to painting in with high gloss white. Had I been more patient (and had more money for paint) I would have painted the wall a flat white first, to make the effect a bit more subtle. But in the long run, I think it still looks great against the "apartment color" wall. :-)
Let me know if these pics don't work, I hotlinked from facebook so there's no telling. I'll add more "professional" pics later - these came off my Droid X.
