Hello Llighty,
Unfortunately I will be Rejecting your map.
The theme is original, however there is a map that features an umbrella as it's main build (Umbrella - Hard)
The build isn't bad, it's simple but shows what you were going for accurately, with nice details.
The parkour is quite varied in the first half, but the second section of the map is very repetitive, mainly consisting of fences, ladders and single blocks. There were a lot of barriers, this made the map very confusing at parts. Try to avoid using so many barriers in the future, and where you need to have them, place something on them like item frames, to clearly show where they're meant to be.
There were a lot of floating jumps, especially in the last section, try to avoid this as it can make the map look quite messy.
The difficulty suits an expert/insane map, and the length is good for an expert map.
Thanks for submitting your map! I hope to see more maps from you in the future.
