Just posting this for reference.

This artist for this at the time of this post is sanmotogoroo, but that's incorrect. It's nekoyashiki pushio.

I assume the artist posted it on Twitter, first and then Pixiv, since the Pixiv upload date is a year later than the current sourced image.

In case anyone has any doubts, this is one of nekoyashiki pushio's artworks with a style that looks similar to this image: post #2542117
