I got the image from steamcommunity but I didn't find the original artist.

I know it's not the steamcommunity uploader because there is another post on acfun from 2020 (the steamcommunity one is from 2022) but the acfun one is smaller than the steamcommunity one so both no one is the artist (neither the steamcommunity uploader nor the acfun uploader are the artists unless the steamcommunity used AI-upscale but I doubt so...)

The image name is "1668793691_插画8.jpg" Idk if it can help tho
