I have been utilizing various AI tools to create variations of my own artwork. Essentially you can feed certain tools images, and they will produce novel images that are similar to the inputs but still unique in some ways.
You can even combine inputs and mix them in new ways. it's a wonderful way to work.
I generated several dozen images of sea life, and then stitched them all together.
That collage served as the foundation of this final image that I drew atop.
