I think the reason they specified "advanced prompter" is because just text to image (supposedly) couldn't get you this image. If you want good images, you need to use more then just prompts. Using image to image (feed the AI an image and prompt) is a basic example. There's controlnet to give it a scetch or depth map. Photoshop and other "traditional" image editing tools are also used.

But this is a garbage example, obviously.
