Hello Qwiiz,
Unfortunately, I will be Rejecting your map.
There isn't really a main theme to your map. In the future, think of a theme and then have a main build that represents that theme, then build your parkour into it, rather than just having jumps floating around the void, as this can look a bit messy.
The parkour has good variety, you used a good variety of blocks and items, creating original and enjoyable jumps.
Some of the direction of the parkour is a bit confusing, and you also used quite a lot of barriers. I would suggest trying to add in a few more signs indicating where to go throughout the map, and also placing something like an item frame on some barriers, just to make it easier to navigate throughout your map.
The length is good for an expert map, and the difficulty is good for a hard/expert map.
Thanks for submitting your map! I hope to see more maps from you in the future.
