Hi there ImJuiceh,
Im sorry to tell ya your map has been rejected.
The THEME is unoriginal, we already have a luckyblock map as Jash and Urothun said above.
The BUILD has one main build but it is along the lines of 3D pixel art. Please try to avoid floating parkour with making it on the main build.
The PARKOUR is lacking in variation, and is too hard of a medium map, but fits the length. Try to add more block varation such as water, flowerpots, trapdoors, etc and make sure to check out the difficulty level of medium maps nowadays.
Thank you for the submission, I hope to see more from you. Have a wonderful day !
