Blue Gonzo is an evolve and upscale. If you open it you can see the history and prompt modification. This was done with an earlier free Dreamshaper model as you will see. I've also had some interesting results with the free version of Stable Diffusion 1.5. Until you get a prompt and a seed that produces an interesting image or effect you can experiment with an inexpensive or free model and then upscale it when you get something better than just random pixels. While this isn't a masterpiece by any stretch of the imagination I find it interesting, it was fun anyway to evolve and upscale.
