It's always interesting to see you workflow process. I'm doing something similar today, in terms of pay with init images. What I'm doing is use dall-e for quick random outputs from a given prompt, to get the "sketches" for the artwork series. Then I upscale them in ESRGAN, it sharpens them and make pop out the detail. Now they are baking in the SME notebook, with the same prompt used in dall-e.
