Hello!
Unfortunately, your map is being rejected.
There is no distinct theme to your map, which makes it difficult to make a proper build/theme/
There is no main build. Create a main build so that you can path the parkour around. You will be able to add details that this map is currently lacking.
The parkour itself fits the length, so good job on that! The parkour is repetitive as there is no variation. Use variation such as heads, slime, water, cocoa beans, ice, glass panes, fences, trapdoors, etc to spread out variation.
We hope to see more maps from you in the future.
Have a good day/night
