Review :
Theme
Not the best theme mostly because there is already some map with a theme closed to your theme (A "Pagoda" themed map just get accepted a few weeks ago, but it's not a big problem)
Build
Pretty good and pretty simple, maybe try to decorate a bit the parkour itself if you can ? (not only a single floating block)
Parkour
Not really good, the parkour is a bit hard for a medium and a bit long, so it's maybe a hard map ?
Try also to put more variation of blocks, not only ladder, normal and fence but some ice, slime or soul sand too for example !
Your parkour is also pretty confusing mostly because a lot of part are can be skip, don't forget that you can increase your speed with /speed or with some potion ! Maybe try to decrease the number of jump to avoid exploit ? Or maybe put some invisible block (do /barrier ) (but do not overused them, and put some sign on it to warn the player).
Miscellaneous
You need to put a wool of the difficulty (Lime : easy, Yellow : medium..) at the end of your parkour bellow the stone pressure plate
You can skip a lot of your parkour by just walking around on every floor (Like kroro said) (Put some invisible block)
Impossible part at the end (Like kroro said) :
My opinion
Not gonna be accepted, mostly because of every exploit, but also try to improve a bit your parkour, because the parkour is the most important thing in a parkour map.
(I'm not a map judger, so their opinion can be different !)
