Similar dataset like I used for Rough Impressions XL ("RI") but drastically reduced and selected for only the top-tier Henri Martin paintings (and 10% other artists) showcasing a style of very thin, longer but still pronounced impasto brush strokes, calling them "ethereal".
Settings:
Sampler: DPM++ 2S a (Scheduler: Normal) or Euler Karras - but you can try out others too (I used alot of DPM++ 25M Karras in the example images)
CFG: 3-6 is what I tested
Steps: 20-25 is what I tested
Strength: 0.8-1.0 is what I tested
Most include prompts for 100% of the style:
painting, impressionism
Try the prompts "sun, sunset (or dawn), sun rays" for a very cool effect :)
Just like with Rough Impressions I like to combine this LoRa with additional artist prompts from the SDXL database, mainly Theo van Rysselberghe (bright strong colors, pointilistic) and Alphonse Osbert (melancholic, mystical) and Andrey Remnev. The prompt would then start with something like "in the style of [Artist]" or "art by [Artist]"
Enjoy!
