Hello Noganog12,
Unfortunately, I will be
Rejecting your map.
The theme isn't original, as there are a lot of biome related maps. The build is accurate to biomes, but it is very small and simple. Try to have one or two main builds, then incorporate the parkour into that, as this will make your map more attractive to look at, also having so much floating parkour can make your map look a bit messy.
The parkour is quite repetitive. You had different jumps throughout which is good, but they felt grouped. What I mean by this, is you would have a sequence of just glass panes, then just regular blocks etc. Try to mix up your jumps a bit more throughout your map, as well as experimenting with a larger variety of blocks and items. This will overall make your map a lot more fun to complete.
The difficulty is good for an easy/medium map, but it is far too long. I would recommend reading
this wiki article which includes the map requirements.
Thanks for submitting your map! I hope to see more maps from you in the future.
