Hey Trash062, here is my critique of the map!
I would say the theme is semi-original, as there is already a map called Nuke in expert, but that map is based on the Call of Duty map. The only problem is that the Nuke expert map ends on a nuke similar to yours. For this course build-wise, it could be better. I'm not sure why but compared to the tent, tank, and military bunker, your Atomic Bomb is MASSIVE. Map makers should always keep scale in mind when building a map! For your parkour, it is mostly varied which is good, but you should throw in some more variation... flower pots, water jumps, ice, soul sand, beds, enchanting tables, etc. There's also a weird barrier section but I think its fine. The parkour matches the difficulty of the map. Good luck!
