Hoi spanieI,
Sorry to tell you that your map have been rejected.
I guess the theme is ok, since we don't have maps like that, and the parkour is also nice, it's varied but maybe a bit hard for a medium (the end is also not possible), the reason why I reject your map is the build, it's really not attractive and plain, and it's because of the theme, I don't know how you can really change the build, so I will just suggest you to pick a better theme next time.
Thanks for submitting your map, would be really good to see more maps from you !
