Oh wow, I had the exact same one! And...the same thing happened to it...the rust looked cool so I was going to keep it, but then it started to fall apart. Meh. Your butterfly crash-landed.
A beautiful photo. I love the broad range of colors, and the subtle blend of cool and warm, along with the glow of the fading sun. There is something very comforting and warm about this photo. Maybe it's the rust and wood and green leaves.
