I regret to inform you that your map is being rejected.
The theme is unoriginal, as we already have a few maps relating to different biomes (FloatingBiomes, Seasons, AdventureInHistory.) Before creating a map, please make sure that the theme has not already been done before by going here and clicking the google doc in the thread: https://manacube.com/threads/parkour-list-with-theme.20194/
The build is quite messy with the structures being small/spread apart, so try having only a few structures, expanded, and grouped closer together, as well as adding more details to them. Also, try to avoid using floating islands.
The parkour is quite repetitive throughout, so be sure to incorporate different jumps throughout your entire map. This may include; heads, water, lava, glass, vines, trapdoors, flower pots, and many other different types of jumps depending on your theme. The length of the course/difficulty of the jumps are okay for the medium difficulty.
Thank you for submitting this map, I would love to see more submissions from you!
