Hello BagelBoi69,
Unfortunately I will be
Rejecting your map.
The theme isn't very original, as there are a lot of maps that feature airplanes, please read over the document in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
The build is good, it is overall detailed and well built, I can see you've put a lot of time and effort into it.
The parkour is quite repetitive, I would recommend experimenting with a larger variety of blocks and items when building jumps, it will make your map overall more enjoyable to complete.
There are a lot of floating jumps, try to implement your jumps more into the build, floating jumps can make maps look quite messy, so try to avoid these in the future.
The difficulty is good for a medium map, and the length is good for a hard map.
Thanks for submitting your map! I hope to see more maps from you in the future.
