Hoi chanfy,
Sorry to tell you that your map have been rejected.
The theme is original, since there is no maps with the same theme. The build however is not good, it's pretty plain and unattractive, there is also some floating blocks, making your map messy, please build your parkour on/in the build, and avoid around. The parkour could be better, it's varied, but I found your map a bit confusing, most on the build, because of the amount of invisible blocks, try to replace them with something else (glass for example) or add more signs on the barrier.
Thanks for submitting your map, would be really good to see more maps from you !
