Generative fill illustrations

Testing out the new 'Generative fill' in the Photoshop Beta I have got to say is pretty impressive. I took some Photoshop landscape illustrations I created that are a few years old. Which I mirrored over to the right and then used Generative Fill to change the layers. This took quite a few minutes for each one. As you can see it works incredibly well, a big time saver. Being able to add extra elements via a simple text prompt such as splash, mountains, and trees, and add red mist is a significant addition to photomontage. At the moment I am only able to get it working for specific types of illustrations such as these landscapes. My anatomical illustrations for example could not change eyes around for some reason. Plus figurative silhouettes kept coming out a mess. I guess in the future there will be different solutions to the varying types of image-making styles. Let me know what you think.
