Hoi chanfy,
Sorry to tell you that your map have been rejected.
The theme is pretty original, since there is no maps with the same theme. The build could be better, there is a little amount of floating jumps, making your map slightly messy, but the main problem in my opinion is the second build, using granite is a bit odd in my opinion, and the back of the build is not finished, making the build less attractive. The parkour is not really good, it's a bit varied, but still repetitive, and too long for an easy in my opinion.
Thanks for submitting your map, would be really good to see more maps from you !
