The lighting and shadows give this image a dark quality creating a sense of foreboding. I was relieved to know that it was an art sculpture I was witnessing!
The degree of abstraction increases the degree of mystery here, Carol. If you had not told us that this image was made in an art museum, I would see it as depicting an aerialist, or a leaper. In any event, you grab not just the eye here, but the mind as well.
