ho caricato l'immagine e inserito il prompt ma quando clicco genera mi esce un messaggio di errore e non genera niente, ditemelo voi qual è il problema

Hey ​@Pietro30856578eu5d 
Thank you for sharing the detailed prompt and the image.

For a project like this you will need to take a number of steps, editing and revising. Unfortunately AI Image Generators are not: one prompt and done. As creatives we need to make revisions.

Photoshop would be my go to tool of choice to make the necessary changes.
