Tried to find 1st party source, but I think the artist nuked.
I'm pretty sure they did. The only other places I've been able to find these images was a twitter account called @notdudlesnudy saying they were archiving the artist's Monster artwork after they nuked their account. The versions posted on the rule34 booru had better quality, probably because they weren't run through twitter twice. Thanks for checking, though.
