Hello CharlieJack,
I regret to inform you that your map is being rejected.
The theme is alright; however, we do have a map with a similar style (City.)
The build was somewhat accurate to what you were going for; however, the buildings are a bit plain. I recommend adding some more block variety to the present structures, and maybe adding some more details on the ground and surrounding the builds.
The parkour is varied throughout, and is incorporated with the theme quite nicely. There were a few tricky jumps (particularly the dispensers) but overall, the length of the map and difficulty of the jumps are good for the expert difficulty!
Thank you for submitting your map, I would love to see more submissions from you!
Have a nice day,
Kristina
