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.
Design/theme: I'm assuming this might be something or a reference from the series 'Doctor Who' but I'm not so certain, I have seen some maps that look like this but I'm not exactly sure what your theme is so I can't really go off of other people's themes compared to yours, I do have to say it does look somewhat unique and seems you put some good detail into your parkour submission, great to see :D
Parkour difficulty/length: For the parkour length it's definitely too long, way too many jumps for medium and too many jumps for even an INSANE Map, I recommend cutting the number of jumps or upping the difficulty of your parkour map, for the parkour variety it's sadly quite bland, you've got some different blocks here and there but they are still pretty simple, I recommend adding more interesting jumps like common head hitters, head jumps, flower pot jumps, etc.
Have a good day!
