There are several other sites or you can install it locally. I like to render my own image and feed it into the program as a source with about 10% variance. It can give you little details that are a pain in the ass, such as normal imperfections you don't want to think about. Why worry about finding a blood overlay when you can use the text commands for the AI to fill it in? The higher you increase the variance the more divorced from the source image. I even fed a selfie into it with mid-variance and got to laugh at the results. AI is great for fun and it does make decent guided art. I doubt it will ever be able to replace human artists who make specific works with detailed customizations. Royo et all have nothing to worry about.
