There are a lot of gorgeous backgrounds available on the marketplace, but most of them are very clearly standalone. A pack of alien cities will be a different alien city in each picture and so on. It would be nice to have pictures that could be used to tell a story through successive images.

Something like - a castle on a misty mountain in the distance, then the front gates of that same castle, then several rooms within that same castle, then a view out the window of that castle looking down over that mountain from the beginning. With that, you could illustrate a whole fairy tale.

Or walking through a city on an alien planet, seeing it first from a distance, then inside the city looking at different buildings, then inside some of the buildings... You could tell a story about exploring this landscape, but it all has to be part of the same landscape.

As it is, there are lots of nice pictures but they don't connect together to form a whole and don't really look like part of the same story.
