Ah, I don’t think there are any weights or parameters you can change for the cubism style in DALL-E.
I’ve tried creating one in Midjourney but it’s quite tricky. In the end I had to create an image of a space marine first and use that as input for a second render with just warhammer and cubism as prompts.
Base image:
Prompt: warhammer space marine painted in a cubist style --s 25
Final image:
Prompt: warhammer::1 cubism::2 --s 50
