I especially like that they all seem to inhabit the same world yes. This would be great for world building of any kind. Do you think there is any specific part of your prompt that had the impact to create this kind of effect?
Honestly I think it was keeping the “styling” prompts the same (volumetric lighting, artstation, concept art, fantasy, intricate) while varying other themes. Sometimes it strayed a little when I removed things so I added them back in. Sometimes I removed them to get a particular look. It’s all just experimentation.
