Hello nasser_919,
Unfortunately, I will be Rejecting your map.
The theme is original, and the build is really good. It's really nice to look at and is overall built very well, so well done!
The parkour isn't great, a lot of it is very repetitive, as you used a lot of normal blocks. You did have a few other types of jumps throughout the map which is good, but you did use a lot of normal blocks to transition between these jumps. Try to experiment with a larger variety of blocks and items when building jumps, 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 more, and avoid having too many jumps floating around the build, as this can make your map look a bit messy.
The length is good for a hard map, and the difficulty is good for a medium map.
Thanks for submitting your map! I hope to see more maps from you in the future.
