the "abstract prompt" (image to prompt) works ok with this. Using Canny (ControlNet) can help a lot with transforming a real image into Dark Fantasy (I recommend Canny: 0.4 and ControlStep: 0-0.8).

Prompt:

If you are having problems with pics coming out weird:

change the prompt in that specific part - make the prompt more clear

(Ex: instead of "his fingers wrapping around the sword" use "he holds the sword")

don't use one super large sentences to describe one thing - break it into pieces

(Ex: instead of "a beautiful woman with red long hair wears a green old cape and sits in a medieval castle" use "a beautiful woman with red long hair, wearing a green cape, sitting in a medieval castle")

don't break the flow of the prompt - write it like a sequence

(Ex: instead of "a beautiful woman, wearing a green cape, sitting in a medieval castle, with red long hair" use "a beautiful woman with red long hair, wearing a green cape, sitting in a medieval castle")
