Hoi iMonkey,
Sorry to tell you that your map have been rejected.
The theme is a bit original, but not totally original since there is already a Library map (but pretty different to your's (Library)), the build is not good, it's not really attractive and pretty plain (We can easily see the use of worldedit for the wall), avoid overusing worldedit and try to add more decoration Inside the build. The parkour could be better, it's varied, but maybe a bit repetitive (There is a lot of "Stairs" jump in your map).
Thanks for submitting your map, wold be really good to see more maps from you !
