Hello!
Unfortunately, your map is being REJECTED.
As previously mentioned above, unfortunately, this theme is unoriginal as we already have many biomes maps.
The build itself does have some good details and texturing! Unfortunately, it does look quite messy. Rather than having a lot of floating islands (which we do not allow), build one main island/build that you can path your parkour around.
The parkour itself is quite inconsistent throughout, with some checkpoints/areas being harder than others. In addition , it is quite repetitive as your variation is in clumps. Use more variation such as heads, cocoa beans, glass panes, trapdoors, minecarts, etc. so that you can space out your variation further.
We hope to see more maps from you in the future.
Have a good day/night
