I regret to inform you that your map is being rejected.
The theme is unoriginal as we already have a map based on a fan (FanPK.)
The build is accurate to the source material so good job on portraying that well.
The parkour is the main concern, for starters it makes use of west-facing piston heads which are not allowed and are frankly just unfun to use in maps; changing them would be best. Some directions would also be good for the big slime and inside the fan (also adding a ladder to make it failsafe would be good.) A lot of repetitive/annoying jumps are used (such as a fence gate blending into the floor as the literal first jump of the map.) Allowing the parkour to feel more natural in the map and not just cutting out a hole in the wall would lead to your map improving drastically! It does fit the hard difficulty nicely.[]
Thank you for submitting this map, I would love to see more submissions from you!
