This is considered pixel art, which isn't accepted on ManaCube anymore. Try to make the build 3D. Most of the parkour is floating, and doesn't look performed properly. I suggest you try to put the parkour on the build(s) instead of around them, or try to improve the parkour as is. https://manacube.com/threads/what-is-block-variation.64601/
I'm not a map judge so my opinions won't affect your submission, this is just feedback. Good luck
