Heya!!
I regret to inform you that your map is REJECTED.
The THEME of your map is original as we don't have any maps based around a monorail, so good job on that!
The BUILD of your map is a problem. While it is somewhat accurate for what you are going for, the build seems a distracting/messy from the monorail build itself. Next time maybe try enlarging the build and have it more based around the monorail itself.
The PARKOUR fits the length and difficulty of a medium map, so good job on that! Your parkour has variance but it feels like blocks are just added for the sake of variance. Next time try adding parkour for a reason and be more creative with it. This is a very hard thing to do, so I recommend looking at recently accepted maps as well as looking at some tips of building parkour on the forums.
Thank you for taking the time to create a map, I hope to see more submissions from you in the future.
