Please note: I'm not a map judge, so my opinion doesn't matter if the map gets rejected or accepted.
First of all you need to have a main build, and a main theme.
The building is lacking of originality, because there are some maps that are kind of similar like Random.
Also the parkour needs to be attached to that build because floating parkour isn't very acceptable.
The parkour is a little varied, which is good, but I think you could have varied it a little more, for example with enchantment tables, brewing stands or heads.
All in all the parkour is fun to do, but it needs a real build, more originality and more variety.
Good Luck!
