I love this game artstyle and I wanted to replicate it. I'm still trying to improve it, but this version is decent enough to be a starting point.
For the new v2 version I refined the dataset to include recent illustrations and focused only on the higher quality illustrations.
For the wai version, 0.8 to 1.0 works well.
For the v1.0 I recommend 0.6-0.8 weight. I trained the v1.0 with ntrMIXIllustriousXL v40 as the base model.
