I can think of a dozen ways this could be useful for my quest, or whatever story you might run that you want to use portraits and landscapes for.

First attempts at males and females
Landscapes are next but so far the images are so gloomy while I love dreamy lush green Miyazaki aesthetics...

 

I am gonna love this for landscape concepts for stories.
