Hello Capsicum,
Unfortunately, I will be Rejecting your map.
The theme is original, and the build is really good. It has a lot of detail and I can tell you've put a lot of time and effort into it, so well done!
The parkour is quite repetitive. You did use a variety of jump styles, however there are a few sections that were very repetitive. For a map of that length, I would suggest trying to make the jumps a little more varied, as you did use a lot of trapdoors, normal blocks and fences. Also try to avoid grouping jumps too much, what I mean by this is that there were some parts that were a sequence of just fences, then just heads, then trapdoors etc, so trying to space out and mix up the jumps more.
A lot of the parkour is floating. Having a lot of floating jumps can make the map overall quite messy, try to implement the jumps into the build more.
You did use a lot of barriers, try to avoid using too many barriers where possible, since this can make the map quite confusing, and also look a bit messy.
The difficulty suits a medium/hard map, and the length suits an expert map.
Thanks for submitting your map! I hope to see more maps from you in the future.
