Heyo! Glad to see a submission from you, and good to see your dedication to making maps! Here are my thoughts on this submission;
THEME:
The theme seems to be unique, so well done in that regard!
BUILD:
Personally, I'm a big fan of the build. I like the way you've done the tree and made it look like a slice cut out of a world. The addition of smaller trees and islands adds to the aesthetic of the build, and the way you build the parkour into the build is done well. Good job!
PARKOUR:
I think that the parkour in this map is decent, but could have been done better. The start was done well but it becomes very basic and the majority is floating, which isn't great. The checkpoints also seem very far apart, meaning you have to do large sections of floating parkour. It also feels fairly easy for a medium map.
Overall, you really just need to make the parkour a bit harder and have less of it floating. Once you've done that, plus adding a couple more checkpoints, I think this map has some great potential! Good luck to you!
