Hoi Lucifr,
Sorry to tell you that your map have been rejected.
The theme could be more original, even if there is no "Autumn" maps, there is already some maps with the same concept (You made SpringFlowers, so I supposed you already expected this for the theme). The build is decent, but maybe a bit messy, avoid adding floating blocks, mostly when they are not really useful for your parkour. The parkour could be better, Faudon already said a lot, it's varied, but feel repetitive at the start, and on the bird, I also think the difficulty of the map is unbalanced, some part were really easy, when some were too hard (The part on the bird for example), be careful ! Last thing, I think the map was a bit confusing because of the amount of invisible blocks, try to lower the amount, with using for example glass.
Thanks for submitting your map, would be really good to see more maps from you !
