Hello DigiDitiX, I am sorry to say your map is being rejected.
Theme: The theme is unoriginal, we have a lot of cave related maps already.
Build: The build is rather simple, the start water section was a bit sad looking in comparison to the rest of the map.
Parkour: The parkour was pretty basic, but my main issue with it was the number of unmarked barrier blocks you used amongst and throughout the build and parkour.
Thanks for taking the time to submit your map, hopefully, you will submit more in the future!
Have a good day, and happy map building- Cele <3
