Hello TricoDoesStuff,
Unfortunately I will be
Rejecting your map,
The theme isn't original, there are already many biome themed maps. I would recommend checking this thread
https://manacube.com/threads/parkour-list-with-theme.20194/ to see which themes have already been done.
The build is nice, and I can tell you put effort into it, however like I already mentioned, the theme is very overused.
The parkour doesn't have any variation. It's all single block jumps. I would suggest experimenting with different blocks and items when building jumps, to make the map more enjoyable to complete.
Almost all the jumps were also floating, in the future, try and factor the jumps more into the build, rather than having them floating around the build. It makes the map overall look a bit messy when the jumps are floating.
Thanks for submitting your map! I hope to see more maps from you in the future.
