A style similar to that of the Hazbin Hotel animated series.
This is a challenging style to be sure, if only because every character has so much detail to it. I highly recommend checking out the sample images for prompt recommendations, as symmetry and overly strong characters can override the style.

Dialing back the strength of a character name can help considerably- as that will help to keep the style at full strength without necessarily having to crank the lora up. (<character name>:0.7) is a pretty decent baseline to start with, and as always feel free to adjust as you see fit.
