Hello,
I'm sorry to inform you that your map has been rejected, the build and theme are very good, but the floating jumps at the beginning make the build look messy and unattractive, I also found that the parkour was too hard for the medium difficulty you were aiming for, there was an abundance of reoccurring jumps such as ladders and "normal" jumps.
In the future when creating maps, please keep in mind to go through and test your jumps after completing the parkour, I also recommend getting other players to test it for you to determine the difficulty, I also recommend attaching more of your parkour to your main build, rather than leaving them floating as it makes the build look unattractive, another thing that I strongly recommend is that you add more variation in your jumps, I personally recommend using blocks such as ice, soul sand, brewing stands, chests, water, etc.
Thank you for taking the time to create and submit your map to the forums, I hope to see more of you in the future.
Luci
