this has been done for a while but just decided to post it now the maze isnt like most mazes a one solution maze it has many different pathways where you can go and end up somewhere else or back where you were yes theirs plenty of dead ends as well.
this is the spawn.
this is where the players enter the maze.
now just pictures of the whole maze.
sorry about the last picture quality had to take it with my phone map of the maze
it hurts my brain to look at that maze let alone attempting to actually complete it... Which might in theory make my brain collapse in on itself creating a black hole which might end life on earth as we know it!
Looks amazing (pardon the pun) but it also looks like it wouldn't be very much fun to play, frankly.
Consider maybe making a maze or series of them with particular goals. For example, you might have regular landmarks in the maze (eg a fountain, statue, hut etc) and have a goal of collecting an item at each landmark (eye of ender for example, equipment for traveling to End with).
I once made a maze where you had to find 5 bars of iron spread across chests to make a minecart, which could act as a key to open a treasure-room door using a detector rail as the "keyhole."
Try and think of ways to make your maze fun for players, to have visual landmarks for bearing, and probably make them "solvable in a certain amount of time" because I doubt it's fun to run around your huge maze there for hours and hours.
