Hoi WambatMagic and ItsRainingMen101,
Sorry to tell you that your map have been rejected.
The theme is not really original, Minecraft blocks maps are pretty overused, and there is already a firework map. After there is no dispenser map, so it's a bit more original, but I still suggest you to pick something more original next time. The build is pretty fine, even if the dispenser is copied from the real dispenser (Same reason as a pixel art, if you don't know what is wrong). The parkour is not really good, it's pretty repetitive, and I think it's too easy for a hard, but too long for a medium. I suggest you to use less normal and ladder jumps, and use more fence, ice, soulsand...
Thanks for submitting your map, would be really good to see more maps from you !
