This style is intended to produce illustrations in the style of the Czech artist Josef Lada. His style is distinguished by a simpler colour palette and black strong contours. It is a bit reminiscent of comic book drawings, but without elements such as motion blurs, etc. LoRA's of this style are already here on Civitai, but only for Flux nd SDXL. Yet it is a style that directly calls for a version in Illustrious.
The generated images have pretty vibrant colors, if you want more muted, choose a smaller cfg.
In combination with LoRA's for characters, Lada's style is slightly suppressed - when the image is focused on the character, the character is rendered more in its original style and Lada's style is more or less only shown in the background, even then the composition looks pretty good (see images with Kion). If you use only this LoRA, it works well with a weight of about 0,8-1, then in combination with other LoRA's it is better to choose a weight higher 1-1,2 (higher weight leads to unnatural colors).
ALSO, IT WORKS BETTER WITH BASIC PONY CHECKPOINT.
