Hello Squach_Duck, I am sorry to say your map is being rejected.
Theme: The theme is not very original or evident, there is already sea temple map which uses similar block varieties, but there isn’t actually much of a theme to what you’ve built so I can't accurately decide how original it is.
Build: There isn’t really a build, just blocks decorating the parkour, as I said above this makes it difficult to actually see a theme or build in your map.
Parkour: The parkour is rather basic, the jumps lack variety and are pretty simple, some block variation other than fences and ladders could be good too.
Difficulty: The difficulty suits medium difficulty, however, it is rather simplistic as said before.
Thanks for taking the time to submit your map, hopefully, you will submit more in the future!
Have a good day, and happy map building- Cele <3
