PatisserieFLUX - YA fiction fantasy book covers and art style. This lora was trained on 3 separate styles of YA fiction covers. Although trigger words are not necessary with FLUX loras, here are the three tags that were used for the individual styles that you can add to your prompt.

trigger word ChouxFLUX - for character focused book covers without ornamentation.
trigger word TarteFLUX - for central object focused book covers with minimal ornamentation.
trigger word MilleFLUX - for typographic focused book covers with heavy ornamentation.

or course these are not fixed and you can mix and match trigger words with subject for varied results.

Sample images were prompted as such:
[trigger word], YA fantasy book cover, titled 'Patisserie FLUX' text "Patisserie FLUX" by 'A.A. Ithriel' text "A.A. Ithriel". [description of cover]

Recommended generation parameters:
Euler - Simple - 25 steps - 3.5 guidance

I've also included in the versions ChouxFLUX as a standalone lora without any text if you want to just generate character portraits in the art style not as a book cover.
