Hello Jtrainbrand, this is just my opinion of your map, and not the official review.
The theme: The theme is unoriginal in my opinion. Although there may not be a map dedicated specifically to the giving tree, there are plenty that revolve around a tree, or trees, and many many floating islands maps.
The build: To be completely honest it's basic and unattractive. The tree is quite literally a bonemealed spruce sapling and shows little effort. I also feel that given the theme the tree should at least play a bigger part in the build.
The parkour: Again, basic, mostly small floating island jumps, and little block variation has been used throughout. I'm not sure it's suitable for the medium difficulty either, more appropriate as an easy map
To improve your map I'd suggest redoing the build to be one main, central object, with a more thoughtfully built tree- perhaps build it in the tree's signature shape, with the branch on the left hanging down. I would also say a revamp of the parkour is necessary.
Good Luck!
