Hey there, before going ahead with your map submission review I'd like to inform you that I'm only giving you my personal opinion/feedback on your parkour map submission and my personal feedback will certainly not affect your parkour map submission in the slightest, I recommend that you take in my feedback to improve your submission if there are any flaws, you don't need to and you're free to ignore me but anyhow, before going ahead I'd like to mention that I'm a Moderator not a Map Judge so this is just my personal opinion and I am not accepting or denying your parkour map as this is only my personal opinion.
Parkour theme/design: For the parkour theme, unfortunately, there's already a handful of plane parkour maps/themes so sadly your map submission is currently unoriginal, though with some tweaking I'm sure you could find a way to make it a little more unique of a map submission, for the detail you did a pretty good job, I can clearly see you put some good effort into your map which is certainly always great to see!
Parkour difficulty/variety: For the difficulty, I feel that some of the jumps may be a little hard for people in the 'EASY' level unfortunately and sadly for the parkour variety your map submission is quite bland, I suggest adding more interesting parkour jumps like flower pot jumps, anvil jumps, chest/enchantment table jumps, etc.
