Hi froggcam, I have some feedback for you.
First of all, this is 3D pixel art, which isn't accepted on ManaCube anymore. Maybe change the skittles from floating like pixel art, to all in a glass jar? That would be kind of cool! Or even better, the skittles just starting to spill out of the opened wrapper.
Secondly, the parkour from the screenshots is repetitive, only because you made sections of different block jumps. Try to instead of have sections, blend it all in!
https://manacube.com/threads/what-is-block-variation.64601/ Also, the parkour looks like it's overlaying the build and looking messy overall. If you were to redo the parkour, make sure not to have it float, because floating parkour has to be done extremely well to be accepted on this server.
I'm not a map judge so my opinions won't affect your submission, this is just feedback. I hope you take it into consideration. Good luck
