This lora can be used on its own as a style, or in conjunction with other styles or concepts. Adding strength will "clean" your style, providing detail reduction as you approach a cute and simple aesthetic. Alternatively, slide the strength the other direction to add detail and complexity, making your generation more painterly!

More strength = more cleaning. Greater negative strength = more detail pollution.
