As the others said, the walls look very world edited and fake.
The map itself looks really small!
Why are walls are only one block thick, and others are like five blocks thick?
And the block pallets for the ground just doesn't fit in.
And I totally agree with Trenly. If your going to remake a place from a book, or at least a movie, things need to be accurate.
Recently I recreated the Willly Wonka factory from the 2005 film, Charlie and the chocolate factory. And in order to recreate something as accurately as possible,I leant that you need to examine each shot of the movie very carefully. I don't believe you did this. I wouldn't really call this a maze runner map. Rather than a 'maze' map.
I'm sorry butt here is allot wrong with this arena. It has been declined.
