Hello!
I regret to inform you that your map has been REJECTED.
Unfortunately the theme is unoriginal as we already have maps based around very similar themes.
The build of your map is a concern. It's lacking depth and detail. Due to the simplicity of the theme, it's quite hard adding in the depth you need.
The parkour itself is too short for a medium map. It did fit the difficulty for the most part though- just a few hard jumps, so good job on that! When making a map be sure to make sure that all jumps are possible in 1.8.9 as you currently have some impossible jumps. To add more variance, use jumps such as fences, water, cocoa beans, trapdoors, minecarts, daylight sensors, doors, cactus, etc to make your parkour more enjoyable and less repetitive.
Thank you for taking your time to submit a map. We hope to see more from you in the future.
Have a good day/night
