This SCP just feels bland to me. A strange, otherworldly maze populated by hostile and interesting creatures is a solid concept, but at this point it just reads like SCP-778 with monsters, and while I like 778, the concept is not made better by repitition.
I would suggest a bit more description of anomalous structures within the maze, but the Foundation seems to suffer an overabundance of bizzarchitecture already as it is, so… Your best bet for improvement, in my eyes at least, is to expand on the maze's inhabitants. Perhaps include a fragment of a first contact log of some sort?
