Hey Ashland,
When you submit a map you need to have some things in mind. Never submit a map that is not ready. Finish it and then submit it.
Your map also needs a theme like all of the accepted parkours.
http://forums.minevast.com/threads/must-read-map-submission-information-format.649/ Go to this link for more information of what a map needs to have. I know you can do better and next time dont submit a map until it is ready because staff will reject or accept this map once you submit it and they cant accept it or reject it if it is not ready.
Since you are new I will give you a tip: Dont make parkour maps with pixel art because they wont accept it. There are too many Parkour courses with pixelarts allready accepted and dont copy themes. I hope this helped. I dont want to sound rude
You can go to the parkour server by typing /parkour to see some allready accepted parkour maps so you can imagine where to place checkpoints, the plate with the wool so people can jump into them, receive gems and go to spawn.
