its breathtaking! But it doesn't look sad to me, in fact, it looks content. Because after all, without humans, the ruins are just slowly going back to nature, where it came from. And just because humans don't speak in-animated object language doesn't mean they can't talk.
To each one of us, the ruins have their effect. Sad, happy, whispering. That is the beauty of us not being equal. I do not consider that the ruins are getting back to nature. These are man made. I do consider Nature is taking back her place. It's different for me. And everything speaks. And have a language. Just because you can't hear it with your ears it doesn't mean it doesn't speak, as you said. But if they could talk, everyone would listen. And not just a few of us.
Sure thing! We all see things differently. But you know, all man-made materials come from the earth originally, so the only difference between made-made and natural materials is the extra step in the making process. Either way around, its the same, still a beautiful portrait of ruins.
