Hello Zach DA Yac! Im here to give you my personal feedback on your map. Please note that I am only a mapper and my opinion has no effect on the final decision whatsoever!
1-Theme || Sadly, there is already many maps with a theme relating to mountains. Some of these include DeathMountain, Icemountain, and Sandmountain. This means that the theme has been used and it is unoriginal. This lowers the chance of the map being accepted.
2-Build || The build isn't the best. It is just a few little bumps in on a big platform. I feel the theme could have been represented a little better but you do have variety in the blocks so good job with that.
3-Parkour || I am unable to play at the moment so I cannot judge the parkour.
Also, when submitting a thread, use the submission format found at the top of the submission page. All in all, good job making this map. I will be rating it a -1 due to the reasons above. Good luck!
