I don't know how much faith we put in SauceNAO searches when it comes to finding artist names, but just in case the information is lost there:

According to SauceNAO, this picture was uploaded by ＠マイマイ (pixiv username: tocky2252) and titled "みどり【塗ってみた】". It was pixiv #38722352, but has been deleted.

Perhaps it's a simple recoloring of post #1646511?

Or maybe, this tocky2252 is an art thief.
