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, let's get right into your parkour map submission review!
First of all, before going ahead, you didn't really specify where your map is located, It's not really that easy to find it from what you added and I would recommend changing it to (/plot v NCZ021 2) <--- This is a direct teleport to your map submission, just makes it easier for map judges to review your submission.
Originality ~ You didn't really specify but it looks like dice to me, I have seen a few dice maps around the place so I'm not too certain on the originality factor of your map submission, It is great to see that you've got some nice variety with the parkour jumps but I would recommend adding some nice head jumps, preferably the skin texture of dice, to make it look cool, do /hdb to access heads.
Difficulty ~ Sadly this is no-where near the difficulty for a Hard map in my opinion and from my experience, this would in the least be a medium map but it's quite small and most of your parkour jumps are pretty small/close together.
Good luck! :)
