Hello Amp__,
Unfortunately, I will be
Rejecting your map.
The theme isn't original, as there are a lot of nature themed maps, as well as a few snow themed maps. Please refer to the document in this thread -
https://manacube.com/threads/parkour-list-with-theme.20194/ to make sure your map idea is original.
There isn't really a main build to this map. Try to have a build that replicates the theme, then incorporate the parkour into that.
The parkour is varied, you used a good variety of blocks and items, making original and enjoyable jumps, which is good.
All of the parkour is floating, considering there isn't really a main build to this map. Having an excessive number of jumps floating around the void can make your map look a bit messy, so try to avoid this where possible.
The length and difficulty suit a medium/hard map.
Thanks for submitting your map! I hope to see more maps from you in the future.
