Hello Xenobite, I am happy to say your map is being accepted!
Theme: The theme is slightly unoriginal as we have a lot of music-themed maps already, but it's separate enough to be accepted as an original theme/build!
Build: The build is pretty neat and accurately displays a rock concert, nice job
Parkour: The parkour was nicely varied jumps wise and had a good pathway throughout the build
Difficulty: The difficulty suited the medium difficulty well, good job!
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
