Result:
Okay, SO! A word of warning, I am NOT anywhere near close to good at parkour so my judgments on certain jumps may not be valid throughout my comment.
Overall your parkour is GREAT and really fun to play, so I am going to give you a
+1 as although later I may seem a little critical, I still think the map was great fun!
Improvements:
The first improvement that could be made (in my opinion) could be this jump at this location:

I think this because although this being an insane map and most people knowing where to go, I ended up a bit lost.
The second improvement that could be make (in my opinion) would be a series of jumps:

Due to it being glass panes, I was unable to see where to jump. I thought at first that it was my texture pack, therefore I changed to the default texture pack and the situation was the same:

That is all, thank you so much for the map experience!
