Hello!
Unfortunately, your map is being rejected.
As mentioned above, the theme is unoriginal.
The build itself is quite cool! The only thing that'd need more shaping is the and texture is the stone section at the second part. In addition, some shaping to the island itself would be needed.
The parkour itself fits the length and difficulty, so good job on that! The only thing you need to think about is your checkpoint placement, there needs to be a few more! Unfortunately, the map is repetitive. You can use more variation such as glass panes, fences, water, trapdoors, daylight sensors, cocoa beans, slimes, etc to space out your variation.
We hope to see more maps from you in the future.
Have a good day/night
