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.
Theme/Detail: Firstly, yeah I need to agree with GamersDecision I don't really know what your theme is and if it's original, I mean I haven't seen a theme/build like this before so I'm assuming that it's original. For the detail, you've added some nice detail to your building and the surrounding area that's nice to see, really makes it look like an amazing map submission, possibly more work on the ceiling/roof though, not sure on the theme so I can't be certain
Parkour difficulty/variety: For your difficulty, I'd say that you've got a fair amount of jumps for a medium map and the jump difficulty does match the medium difficulty which is great to see. Good parkour variety also, you certainly used some nice unique blocks which are great to see, I'm gonna agree with Gamersdecision it's possible a tad short but that's just my opinion,
good luck! :)
