If you follow the left curve of the roof of the Coliseum into the cloud, you'll see a little wisp just to the left of the tallest "flame." If you look at the tallest flame on the right, you'll see the same wisp (scrunched a bit, as is the rest of the right cloud, which was also rotated). The same is true for all of the other branches/wisps off those two main "flames"; they all match a corresponding wisp on the opposite cloud.

Again, that's beside the point to a degree, but no one looking at the image should think it is "as captured."

I'm curious what the original looked like. It was only after a commenter above mentioned the cloned clouds that I realized the two main cloud "flames" that dominate the photo are indeed copies of each other.

I guess I like it fine as a Photoshop job, but knowing that the clouds didn't look anything like that detracts a bit from the impact of the image. It's still very pretty, though!
