Hello ArteSis,
Unfortunately, I will be
Rejecting your map.
The theme isn't original, as there are a couple of Harry Potter maps already, and one that looks very similar
(Hogwarts - Insane donator) Please refer to the document in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
The build isn't great, since it's pixel art. Unfortunately, we no longer accept maps that have pixel art as the main build, however, you may use pixel art as decoration in your map.
The parkour is quite repetitive. You did use a few different styles of jumps which is good, but you did group a lot of your jumps. What I mean by this, is you would have a sequence of just normal blocks, then just ladders, etc. Try to mix up your jumps a bit more throughout your map, and experiment with a larger variety of blocks and items, as this will make your map overall more enjoyable to complete.
A lot of the parkour is floating, try to implement the parkour into the build a bit more, as having an excessive number of floating jumps can make your map look quite messy.
The length is good for a hard/expert map, and the difficulty is good for a medium
Thanks for submitting your map! I hope to see more maps from you in the future.
