hi! unrelated to rentry ^^', danbooru is like a gallery instead of a social media platform, the artist is lunar_815 on twitter (https://x.com/Lunar_815/status/1613540271635181571 <- link to the direct post) and they dont allow usage of their artwork. the specific one you're using is a commission. apologies if this comes off as rude, i just wanted to let you know 🙇
