Sadly your map has been rejected!
The pixel art, while good, is very basic when adding parkour to the mix, and is nothing unique compared to other pixel art builds that have been made (See Majora's Mask Map, Handsome Squidward and others).
Try to make a map theme that isn't about pixel art. You become so limited when all you can produce is ladder parkour on a person. Try to be more creative!
