-1 I agree with Rap here, these trees need to be hand-made not spawned in by sapling, the ground needs more block variety, and the parkour is super floaty as said above. The theme is sorta original, as there are a few tree / nature maps, but none about Team Trees, the parkour fits the difficulty, but could use more variety (consider using blocks such as soul sand/ice/brewing stands/enchanting tables/anvils/water/vines/fences/chests/stairs and fence gates) If you can fix these issues before it is processed, I'll happily re-evaluate your map
Otherwise, Good Luck
