My preference : 1.3>1.1>1.5
Highly recommended:
ratkin, ratkin_ears, ratkin_tail, ratkin_hairstyle in prompt and
monochrome, greyscale, black background, chibi, forehead, bald in negative prompt
Negative prompt above is highly recommended because of the feature of the dataset.
After I run all the posts, I changed the Lora file name for easy understanding. Better pay attention when copy the generation data.
There will be more.
