Hey there, first of all, this is just some of my personal feedback and I will be reviewing your updated version after you made some of your changes on your ManaCube parkour map submission. If I criticize you please don't take it seriously as I just want to help you improve on your map submission. First of all for the warp/location to your plot its easier if you just type the full teleport command, you just did /visit Funish 2 which actually doesn't work/is an incorrect command, I would just suggest changing it to (/plot v Funish 2) Makes it easier for map judges to check on your map :)
Originality ~ Sadly I've seen a few chicken map submissions on parkour before so sadly your idea is not creative/original which would make it quite a struggle to get accepted, I suggest revamping your build to make it more unique and different from others, will most likely up your chances of being accepted.
Details ~ One of the most important parts about a map submission second to the actual parkour, your map always needs to look fairly decent. Sadly your map doesn't really contain much detail at all and I definitely believe that you can improve your submission by just making some changes here and there, possibly making the clouds more detailed, adding some colorful blocks, making the chicken bigger/more detailed, (just some of my personal suggestions for your map submission).
Block Variety ~ First thing I noticed when I teleported to your build on parkour is that your parkour is pretty simple and doesn't really have much variety, I mean you got a slime block jump and a few fences jumps here and there but there's definitely many ways that you can make your map more interesting. I would suggest adding some head hitting blocks, soul sand jumps, enchantment table jumps, ladder jumps, and the rest is up to your determination and imagination!
Difficulty ~ Personally even for an EASY map your build doesn't have that many jumps, I quickly realized that you have a handful of quite hard/infuriating jumps that would be commonly used for medium/hard maps instead, for example, the strafe jump around the chickens head seemed like a quite hard jump, just my personal experience :)
Best of luck on your map submission! :)
