Snake reaching for sky?

Quentin was on the phone with me last evening when he started remarking on a Work of Art that was located alone a nearby walkway. He decided to take a picture of it and as soon as I hung up, my phone notified me that it had come through.

This is it.

Well, this is a phone photo and, even enhanced, the middle portion blends in with the tree. However, you get the idea. I’m not certain the idea I’m getting is the idea the artist intended.
