Seeking the artist that drew this map so I can credit them

Edited to update: SOLVED! Thank you!

I have a map mystery. I found a map somewhere online in 2017. I used it recently for a game and wanted to blog about the map, but I can't figure out who the author is to credit them.

I have only three clues:
1. An artist's mark that I don't recognize
2. They didn't use hatching, they used open circles/rocks, dots for the walls and shading. So this isn't a Dyson Logos map.
3. Google image search pointed me to Pinterest pins that link to here: https://3.bp.blogspot.com/-ibOymkTLD...rse_hi-res.png - but I can't find the associated blog. The filename is "sac_2017-05_mazeverse_hi-res.png".

Does this watermark/artist mark, or map look familiar?

Thank you in advance!
