Hello ChrisATX,
I like this map, my biggest concern would be the theme, there aren't any maps that are the exact same theme, but the build looks like it's biome themed, which there are already many maps in that category (Biomes - medium, BiomesPK - insane, and some others)
The parkour is good, I would suggest using more variety in the style of jump you use, rather than making a majority single block jumps, even though I know it would be difficult since you had limited space with the build. I do like the way you put the parkour into the build rather than having floating jumps, but as I previously mentioned this gives you limited variety in the parkour itself considering the build isn't very big, and the different levels in the map are tight spaces so not much room to do many unique jumps.
Good luck! :)
