Hello Shio12,
Unfortunately I will be
Rejecting your map.
The theme is original, and the build is really good, all I would suggest with the build is using more shades of different colored blocks, to add more detail to it, but that isn't a huge issue.
The parkour is quite repetitive at times, there were a few sections that had a good variety of jumps, but others that were very repetitive. Try to maintain variety throughout the whole map.
The length is too long for a hard, and possibly a bit long for an expert. Please refer to this thread
https://manacube.com/threads/must-read-map-submission-information-format.649/ when building and submitting maps, so your map can fit the guidelines.
The difficulty was suited to a hard map.
Thanks for submitting your map! I hope to see more maps from you in the future.
