What does a muse look like?

I recently saw a rant about the unsatisfactoryness of the Spectrum sf art award, and when I looked at the award, my first thought was "That doesn't look anything like a muse", but I don't have a clear idea of what a Muse does look like. (I've got a negative imagination-- I'm sure I've never seen a satisfactory representation of a hobbit, but that doesn't mean I know what a good representation would be.)

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?
