"Away in a manger no crib for a bed..."
This one does not have a trigger. And may require some imaginative florid prompts (I used an AI chat service to help with some of my prompts).
I included many types of nativities, table top, wooden, polystone/resin, graphic illustrations, oil paintings, funny action figure dioramas, Christmas lights tableaux's, the awful modern art one the Vatican got in trouble for, oh and one made of meat. There's about 30 in the dataset.
Also, keeping it simple might be the way to go as well.
