Hoi xHonee,
Sorry to tell you that your map have been rejected.
The theme is not really original, because there is already some "Mushroom" or "Forest" maps. The build is decent, but maybe a bit messy, because there is a lot of little floating blocks, and all your builds are scattered, try build on/in one main build. The parkour is not really good, it's really repetitive (Almost only normal jumps), try to use some ice, iron bars, fence, slimes.. and it's pretty hard for an easy in my opinion.
Thanks for submitting your map, would be really good to see more maps from you !
