Hoi DunchLunch,
Sorry to tell you that your map have been rejected.
The theme is not original, there is already a lot of Minecraft themed maps (even with some of the giant blocks you used), so please pick a better theme next time ! The build could be better, the giant blocks looks decent I guess (Still feel a bit like a pixel art, especially the emerald), but the build looks a bit messy, because of the floating jumps, try building your parkour on/in a main build, and avoid scattered builds. The parkour is not really good, while it's a bit varied, I still think it's quite repetitive, try using more iron bars, fence, slimes... and less normal and ladders.
Thanks for submitting your map, would be really good to see more maps from you !
