Hoi rmc22,
Sorry to tell you that your map have been rejected.
The theme like I said above is not original, after making biomes in bottle is a bit more original, but I still think you can choose something else. The build could be better, I think your map looks messy, because there is 6 builds scattered, the parkour is interesting, it's varied, but maybe too long for a hard, but too easy for an expert.
Thanks for submitting your map, would be really good to see more maps from you !
