Hello Saltys_Bleach,
Unfortunately I will be
Rejecting your map.
The theme isn't original, as it falls under the biomes theme. Please check this thread
https://manacube.com/threads/parkour-list-with-theme.20194/ to see which themes have already been done, to make sure your map idea is original.
The build is good, it has good detail, and I can see you've put a lot of effort into it.
The parkour doesn't have much variety, most of it is single blocks factored into the build, I also found it quite confusing, I would suggest placing signs or coloured carpets to make a clearer path of where to go.
The length suits an easy/medium map, and the difficulty suits an easy map.
Thanks for submitting your map! I hope to see more maps from you in the future.
