Hey there, for the [plot location] section in the format that you used for your map submission you only used your username which could make it a hassle for Map Judges to get to your plot location, I would suggest renaming it to (/plot v firenight 1) Just makes it easier for staff who are reviewing your map to make their final decision. Also before going on, I'm just a moderator, not a map judge so this comment/feedback does not affect the final decision of your map submission, you can either cast aside or accept my feedback, nonetheless let's get into this! ;)
Details ~ Your build from the first glance seems alright, I mean you've got some detail in areas and it certainly isn't that bland when it comes to this, I would have suggested that you added more texture to the planets because they're just one block and it seems a little boring from a distance, you definitely could make some cool unique planets if you're creative and put enough time into the detailing.
Originality ~ Sadly your theme is certainly not the origin and I've seen many similar maps with the same theme that you've chosen for your map design, caseyclosed listed them above. I do believe that if you revamped your map and added some new things it could be a little different and a little more unique than the other similar map designs/submissions.
Block variety ~ Your parkour/block variety is quite simple and only really consists of large/solid blocks, as Casey mentioned I suggest adding bed jumps, soul sand jumps, fence/iron bar jumps, slime block jumps, cake/enchantment table jumps, etc. You've done a good job with this map and I can see that it took quite some time to design/create, I wish you the best of luck with your parkour map submission! :)
