Unfortunately, I will beREJECTING this map submission.
Theme: As we have no maps themed after a tightrope, this is most definitely an originally themed map submission. Good job on picking out something new!
Build: Personally, I don't see a build on this map. It's a bunch of parkour floating in the sky. If your theme is a tight rope, you have to try much harder than this. You have to try to create an actual tight rope and then integrate your parkour into it.
Parkour: The parkour was not fitting for any difficulty as it was super short and easy. I was left wanting more. Furthermore, the parkour was also quite repetitive (the back to back head jumps or brewing stand jumps). It just wasn't very fun to do. Try to incorporate a wider variety of blocks/jumps into your parkour so it's more fun to do!
I hope you take these criticisms into consideration when submitting maps in the future, good luck
