Francisco Goya is arguably the most important Spanish painter of all time, and he holds two unique titles.The Last of the Old Masters and First of the Modern Masters. The alpha and omega, if you will.
Way back when, I released a 1.5 version based on Goya's work. In fact it was my very first style model. It went on to win 3rd place in the style contest, and it bought me a shiny new SSD, which I desperately needed at the time. I studied many artists during my years in art schools, but Goya's work was definitely one of the ones that stuck with me on deeper more disturbing level. So I am always happy to pay tribute to it.
This model is different from the original 1.5 model, as Flux tends to do a bit more over-correction, and some of the original style sometimes gets lost.
I recommend keeping the weight above 1, but you can get other unique looking paintings if you lower it.
Easiest way to prompt is to write
" The image is a detailed classical oil painting of ____subject here___"
Then add any flares and caveats describing pretty much anything you want.
