Hello Rhett_Robin,
Unfortunately, I will be
Rejecting your map.
The theme isn't original, as there are a lot of nature/floating island themed maps already. Please refer to the document in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
The build isn't great. It feels quite blocky, especially on the islands. I would suggest trying to add a bit more shape and definition to it.
The parkour is quite repetitive. You used a lot of normal blocks, fences and ladders. You also grouped a lot of your jumps. What I mean by this, is that you would have a sequence of just ladders, then just normal blocks etc. Try to mix up your jumps a bit more, as well as experimenting with a larger variety of blocks and items, to create enjoyable and original jumps.
The difficulty is good for an easy/medium map, but the length is too long. Please read over this thread
https://manacube.com/threads/must-read-map-submission-information-format.649/ to make sure your map fits within the requirements.
Thanks for submitting your map! I hope to see more maps from you in the future.
