Merging a few of my Flux models, we're looking for a painting style, but something that leans more illustrative than classical fine art - quick work that gets the job done, often with strong outlining and bold coloring.
Long text descriptions may result in purely photographic outputs (the LoRA's influence on these can still be quite positive) but you should stay on course with the illustrative painting style with terms such as 'illustrated' or 'painting'.
