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/detail: Sadly as Dancyspoon mentioned above your theme isn't technically original unfortunately, there's already quite a handful of desert-themed maps. As for the detail, as dancyspoon mentioned it's a little confusing and not sure exactly what I'm looking at but it's a bit basic, I suggest adding more detail.
Parkour difficulty/variety: For the parkour variety, I can see that you attempted to add some variety but its still quite plain in my opinion, for the difficulty, I mean I guess it does match medium difficulty so good job on that, good luck! :)
