Hoi Merwic,
Sorry to tell you that your map have been rejected.
The theme is not good, as we already have "Bookshelves/Library" maps (Bookshelves, Library), so please be careful next time ! The build is not really good, it's really messy because almost the whole map is floating, please try building your parkour on/in aa single main build, and not floating around. The parkour is not good too, it's really confusing, as there is a lot of path in your map, and repetitive, as it's mostly normal, ladder and fence jumps, please try using more blocks, like ice, soul sand, iron bars.. and not in a straight line, also I think the parkour is a bit too long for an easy, please try aiming between 20 and 40 jumps for an easy map.
Thanks for submitting your map, would be really good to see more maps from you !
