Model based on style of Azuma Yasao (AzumaArts) - https://bsky.app/profile/azumaarts.bsky.social
Main trigger word - azumastyle,
Optional - painting, painterly, - not required but seems to make thing much prettier and closer to style. Can also help to reduce the shiny-ness of the style... i think.
Adding shiny in negatives can help too.
Tested on WAI v1.3 which preserves the original style very well.
I made it for myself initially so watermarks can pop sometimes. They are not that often and noticable anyways but you can try watermark, text, artist name to negatives.
Hope you enjoy.
