This is a model trained on all background paintings that appear behind the leaders in Civilization VI. Some tinkering and prompt bending might be necessary to get exactly what you're looking for, but I think it's fairly versatile as is.
It's pretty arbitrary but in for the most part I've trained the model on this type of prompting:
Main focus, details around main focus, background, general vibe/time of day, trigger word
Example prompt:
A fishing hut on the riverbank, a small sailboat tied to a wooden bridge, hanging vines and forests in the background, bayou swamp landscape, Civ6BG painting style
I'm planning on making a model for leader portraits, but I might go even further and train other Civ-related models as well. Hope you like it!
