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: Hey there for your theme unfortunately I'm going to be giving your theme a -1, sadly we've already got a couple of parkour maps that look like a forest/incorporate that type of design. For your parkour detail, you did an extremely basic job, I don't really see any detail on your map submission, I suggest adding some trees, possible a house, etc.
Parkour variety/difficulty: After personally testing out your map submission I've got to say that it may have the length of a MEDIUM map submission but the parkour difficulty is most likely the same as an EASY parkour map submission. You basically used all floating block parkour which ruins your map submission and makes it look very messy in my opinion, your parkour variety is very basic and you don't really use any significant blocks. I suggest adding flower pot parkour, chest/enchantment table parkour, cactus parkour, etc.
Good luck!
