Hello valdemar_borch,
Unfortunately, I will be
Rejecting your map.
The theme isn't very original, as it mainly looks like it's biome themed. 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 okay, it is nicely detailed in some areas.
The parkour is very repetitive. You did group a lot of jumps, and a lot of jumps were normal blocks. What I mean by grouping, is that you would have a sequence of just normal blocks, then just fences etc. Try to experiment with a larger variety of blocks and items to create original and enjoyable jumps, also try to mix up your jumps a bit more, to make your map overall more enjoyable to complete.
A lot of the jumps are floating. Try to avoid having too many jumps floating around the build and the void, as this can make your map look quite messy.
The difficulty is good for an easy/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.
