Inspired by my father. Dad, if somehow against all unlikely odds you've figured out stable diffusion and are here reading this, enjoy this style!
Here's a lora art style of my (and my father's) favorite landscape artist, George Bellows. I hope folks enjoy it, I certainly will! You can use "George Bellows", "American Realism" (though this will often put little American flags / USA style in places, which fits the era / location of the original art), "oil on canvas", or "1900" to trigger the style. Or, just run the lora and see what fun stuff happens.
NOTE: "American Realism" does not mean "Realistic" - it is a specific early-mid 1900s art style / school that George Bellows was a major foundational part of. This will not make "realistic" images, but rather "Realism art" images.
Example images were at strength 1, but feel free to play around with it to see the lower strength results (I would not recommend going higher than 1.1 or so).
