Hello Valoyre,
I regret to inform you that your map is being rejected.
There isn't really a main theme, so try to make your map around a proper object or environment.
The build is quite messy and hard to identify, so be sure to make one or a few structures that are easy to identify, and add plenty of detail to them.
The parkour is quite repetitive throughout, so please try to incorporate different jump styles throughout your entire map. The length of the course is a bit long for the difficulty, but the jumps fit the difficulty.
Thank you for submitting this map, I would love to see more submissions from you!
