A muse (a personal muse, not a goddess of an art) should look as though it will come in close and go away at its own will, but I can't think of how you'd express the idea in a single statue.
My muse (or at least something in the back of my head) has recommended a mass of swirling colors, and if you wanted a fantasy award statue, fantasy creatures could be worked into the colors. Still, anyone have a human or humanoid who looks either like your muse or who expresses the idea of a muse for people in general?
