The prompts are usually quite simple, when working with Disco, it's mostly the tweaking of the settings that really give it its natural spin!

The initial Stable prompt for the first image was :
portrait of a creature, octane render, azur marble and ivory hard surface sci-fi design, subtle saphire accents, ivory rococo, sculpted by nihei, melmoth, beksinski, craig mullins, shinkawa, del toro, zawadski, giger, biomechanics photorealistic hyperdetailed, mythological gorgon, anticosmic, amorphous eldritch shoggoth, bloodborne nightmare

And the Disco Diffusion prompts, for each slice, variate around this one :
