This model is trained on various oil paintings hand picked by me from metmuseum.org
It exceeds at creating landscape imagery, sometimes struggles with hands and faces.
I highly recommend using a Face and Hand Detailer pipeline!
Also, It tends to try and create "ugly" people, since paintings back then had that kind of style. They also skew towards being a little chubby, therefore I recommend putting stuff like "curvy" in the negative prompt.
High steps (35+) recommended! I got best results with DPM++ 2M Karras.
