Your comment sticks with me because the art generated here does look very ai generated (the lack of any consistency between something basic like a building window sticks out) and I disagree it’s indistinguishable from professional artists.

That said it reminds me quite stingingly of the work of manga artist Tsutomu Nihe whose works is quite literally about characters going through infinitely large Lovecraft-esq superstructures generated by machines
