Since Iizuki Tasuku‘s style has changed from beginning. The dataset is based on Hoshi Ori Yume Mirai, Seikishi Melty ☆ Lovers, Niizuma LOVELY x CATION, Onee-chan no Yuuwaku, Suiren to Shion and other illustrations.
I've tested it with a few models, including AOM2 and AnythingV3, and it works well.
As for the weight, sweet spots seems to be between 0.8 and 1.0.
