I really adore this artist for his serene drawings, so there it is - Tinyshoya-sensei (or xiaoyexiaoye) LoRA (WIP, I think, since it's my first time using CivitAI for training).

EDIT: It seems to work well! By the way, to see the LoRA and examples, you need to disable X and XXX with this EYE icon in the upper right corner. :)
