Hoi Dritic,
I'll be giving your map a -1, for the following reasons:
The theme for your map is unoriginal, as there are a lot of biomes and islands related maps. Also, the build is not really good looking and islands are far away from each other.
About the parkour, it is not varied at all, you have only used wool, fences and quartz slabs, sometimes making 2 jumps variation. Another thing to add is that your parkour is way too long for an easy map, making it not fitting for an Easy difficulty, even though the jumps themselves may fit the diffculty,
Lastly, avoid making all your jumps floating, it makes the map look less appealing and you don't get to enjoy the build.
¡Good Luck! ❤
