Hi there delvepower,
Im sorry to tell ya your map has been rejected.
The THEME of the map is original so good on you for that !
The BUILD is a bit unpolished. It could have some different blocks used for texturing on the outside as well as more detailing on the inside. Providing train details such as seats and even a main area for a conductor would elevate the build a lot.
The PARKOUR is fitting length of a medium but is inconsistent and lacks variation. The parkour needs to fit more of the difficulty of a medium, which you can observe with the recent mediums and the parkour needs more variation in jumps rather than a repeat of jumps over and over again (such as the outside with the same blocks).
Thank you for the submission, I hope to see more from you. Have a wonderful day !
