Hello,
Unfortunately, your map is being rejected.
The theme is original for the most part, so good job on that!
The build is currently considered 3D pixel art which is no longer allowed. I would suggest building two organics to show the contrast between the "two faces". You will be able to build depth and texture that this build is currently lacking too.
The parkour fits the length and difficulty for the most part so good job on that! The parkour does feel slightly repetitive unfortunately. Spread your variation out & use more variation such as glass pane, water, minecarts, trapdoors, doors, piston heads, soul sand, ice, cocoa beans etc to make the parkour more enjoyable.
We hope to see more maps from you in the future.
Have a wonderful day/night!
