Maki Zenin made by Zuli. I’m trying to find the source (and artist) of this artwork.

I first saw this image on Pinterest, which is notorious for reposting, and thus a very unreliable source. So I used the Google reverse image search to find the ACTUAL original source, thinking it could be easy. It turns out it wasn’t. The only sources it gave me were Pinterest posts. No Twitter, no Danbouru, no Pixiv, no Tumblr, no other non-Pinterest app. Not even SauceNao or Tineye were able to find the source of this image. What happened to the creator, and how can I hopefully find the original source of this artwork? Did the artist delete their social-media account(s), or I just didn’t search deep enough? If you have the slightest clue about where can I locate the original source of this artwork, please, tell me!
