Heya BouncyBonBon!
Sadly, your map is being rejected.
The THEME is unoriginal, as we already have large Minecraft block/Minecraft themed maps on the server.
The BUILD is lacking in detail and depth. It is also very spread out and floating. Try to create a main build that will make the map come together a lot more, as it looks very messy. As well, your map consists of mainly 3D pixel art. When creating something, ensure that it does not count as 3D pixel art.
The PARKOUR is mainly floating and is messy. Try to incorporate your parkour around a main build. Sadly, the length is too short for an easy and the difficulty is inconsistent, try to balance these out. The parkour is unvaried so try to incorporate different blocks into your jumps.
Thank you for taking the time to create a map, I hope to see more submissions from you in the future.
