The theme isn't really related to the map as Inktest said, but the theme of modern building has been done quite a bit, so I wouldn't say it's very original if that's what you were going for.
The parkour is very short for a medium; using the ladder tower, you can complete the map in just 13 jumps! You want around 3x that in a medium map, if not more. It's also confusing, with random jumps added that don't take you anywhere, and extremely easy, with jumps that would be considered easy even in an Easy map.
The build is... well, not really there. It's just floating blocks with a few 1x1 towers.
Overall, I'll have to give the map a -1, unfortunately.
Keep in mind, I am not an official map judge; take my review as that of a normal member of the community <3
