The bubble was already there, but It was literally just a circle. The rest of it I did by hand, from the pink to the drawing. But you have to zoom to really see the detail.
THe hair was jet black, so I did change that, and I tried out some lighting effects I learned from Zenron's Tut.
I'm not sure of why I blurred it, I just thought it'd look good. I blurred the bottom though, to put the focus on the Bubble, like you said.
