Hello,
Unfortunately, your map submission has been REJECTED. Here is my input:
Theme: We don't have any spike-themed maps, but as Noah said the floating island theme is unoriginal - be sure to check the Parkour List before building a map to make sure your idea is unique.
Build: The build was decent. I like the shaping of the spike, but the build did not have much block variety or detail. The top of the build was very boring and it would've been nice to have something cool-looking up there instead of just a tree (I did like your tree though).
Parkour: The parkour was the right length of an EXPERT map, but the majority of the map was too easy. To add onto that, there was quite a bit of floating parkour (especially in the beginning) which made your build look quite messy - I would like to see you incorporate more of the parkour into the build. The parkour was somewhat varied, with chests, ladders, blocks/walls and trapdoors, but you could use a bit more variety. Try to reduce the amount of ladder jumps and instead add jumps with water, ice, soul sand, heads, lily pads, anvils, flower pots, etc. to make your parkour more interesting.
I hope to see more map submissions from you in the future, and have a great day!
