Unfortunately, I will be REJECTING this map submission.
Theme: I don't see a theme on this map. And, the name of your map doesn't help me as it's just the initials of your username. It's just a bunch of different floating jumps and Redstone contraptions with no purpose or focus. It's not very original.
Build: In my opinion, there's a lack of a build on this map. As I said above it's just parkour and Redstone. There's no attempt to portray a theme (if there was one), no central structure, and no detailing/shaping. It's just parkour, really. We don't want to have solely-parkour maps, that's not what ManaCube Parkour is. You want to create a build and integrate your parkour into it.
Parkour: For starters, you can't just say that your parkour is one of three difficulties. That defeats the purpose of each difficulty having to be of a certain length and difficulty. The parkour itself is as hard as a medium but it's way too long for that difficulty. You really have to cut back on a lot of jumps to fit the 40-60 jump range of the medium difficulty. Furthermore, your parkour was incredibly repetitive to do as you utilized the same jumps consecutively. There are just so many segments where it was just the same thing over and over again (ladder segment, iron bar segment, barrier segment, and, especially, the final quartz segment). You need to be more creative and try to make each 1-3 jumps unique. This just wasn't fun to do.
I hope you take these criticisms into consideration when submitting maps in the future, good luck!
