Putting it together

This silhouette, from 7's photostream has several elements of good composition and lighting all working together to make a great photo. Can you find three distinct layers of depth in this image? Sometimes this can be done best with a wide-angle lens and strong composition choices.

In the photo below from Pro-Zak's photostream, you'll see another silhouette, wide-angle shot with great lighting and a 30 second exposure. This photo breaks some rules about centering the subject but that's one of the things I like about it.
