Does anyone know the art/artist source to this?
Reverse image searches on Google, SauceNao, TinEye and Yandex yield no results, it has also never been posted on 4chan before based on the archives (desu, archived.moe, b4k) not having results when the image hash is checked. After checking boorus for relevant tags I found the character is Daiwa Scarlet from Umamusume. The file name is Twitter-based (it's still a working twimg link) and the specific lettering seems to be June.31st-July.1st of 2020 but I've been struggling to find it with those specifications on Twitter with the character's name and series tags. I got the image from a friend who doesn't know the source.
