Hello! I'm going to give you some critiques on your map. While I am a parkour mod, I have no say in whether or not this gets denied or accepted as I am not a Map Judge, so take my criticisms and approval as that of a parkour player, not a staff member.
I'm going to give this map submission a -1. The theme, Graveyard, is not original as there is already a graveyard-themed map (
Graveyard). The build itself isn't great, just a simple tombstone. I would make sure to add details and really make your build stand out with some textures as well.
For the parkour, the number one problem with it is that a lot of the parkour on this map is floating. ManaCube has moved away from floating parkour maps and now maps tend to only be accepted if they have a main build. This means that instead of parkour floating up to a tombstone, the whole map is a graveyard that you parkour around/on. Another issue with the parkour is that it looks very repetitive (seems like its basically just block/ice jumps in the beginning and ladders at the end). Try to mix it up a little by incorporating vines, heads, anvils, chests, lily pads, soul sand, iron bars, flower pots, etc. to your map to really make the parkour interesting and fun to play.
Be sure to check the map list (I'll link it below) before building anything to make sure your idea is original, and you can always check /warp beta or any of the newer maps (they tend to have very low global completion counts) if you want to see some ideas of varied parkour jumps. I'm also down to help you build parkour or to teach you some jumps myself to help you be more successful in future submissions (which I hope you do :D). If you want help feel free to message me on Discord (PyroTortilla#0553) or start a conversation with me here on the forums and I'll get back to you ASAP.
Good luck!
