NGL, not really sure what to name this style. Basically its a style that has simple colors/shading, as well as a rough feeling. In testing, I've found that it works well by itself, or in conjunction with other lora for unique looks.
I usually run this at ~1.0

You can add the tag "sketch" to the positive prompt for more wild lines, or to the negative if you are more interested in the rough coloring/shading.
