Heya,
I regret to inform you that your map has been REJECTED.
The theme is unoriginal as we already have many maps based on the end, the nether and general minecraft biomes.
The build does have some detail so good job on that! The main concern is the shaping of your build- it is lacking depth to it. Try to have a large main build that has a detailed shaping as right now it is a rectangular shape.
The parkour fits the length and difficulty of an easy map so good job on that! There is one slime/piston contraption that is not allowed (in the end portal) so please be careful if you create another map. Sadly the parkour is repetitive. Add more variance such as heads, water, glass panes, fences, trapdoors, etc to spread out your variation more.
We hope to see more maps from you in the future!
Have a good day/night
-Hayley
