pourquoi lorsque je demande de donner un effet aquarelle tendance couleurs sanguines et crayon a une photo, j'ai une retour Chargement impossible

Hey ​@Loic_DENIEUL8224 
Just to add a bit to what ​@Peru Bob  mentioned.

Providing your full prompt would be most beneficial.

Firefly won’t do anything that entails violence. (I don’t make the rules.)
You could try the partner models. 
Or 
Change the prompt to:
Use reference image, apply a pencil and dark red watercolour effect.

Cheers
Nate

What is the full prompt?
