Ann King Painting

I'm trying to decide if this painting is done, or if I need to do something more to it. It's for the Ann King Memorial Show at Topanga Canyon Gallery, and it's a silhouette of Ann. 26" x 38" or so. It's wrinkly because I haven't stretched it yet. I kind of like the simplicity, and I'm leaning towards not messing it up by overworking it.
