Hey there jack103,
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, let's get right into your parkour map submission review!
Originality ~ Hey there, firstly from my experience this design is 100% original, your map looks amazing and you certainly, from my perspective did a great job with the theme/design on your parkour map submission, I commend you for the effort on that.
Parkour variety ~ 45 jumps is a fair amount for a medium map, possibly a little more would make it complete, on the difficulty of the parkour section your map certainly does have some decently hard jumps and your parkour does have some nice variety with the jumps which is always good to see!
I wish you the best of luck! :)
