The build is very nice, it's pretty much perfectly accurate to the real thing, so amazing job on that!
The theme is original as well, there's no maps based on Castle Clash (although there are 2 COC/CR maps, but they look very different and technically are not the same game although they are similar).
The parkour is a bit unbalanced in some areas (e.g the first two jumps and the stretch from the invis neup to the minecart inside [they're overly hard compared to the rest of the map, in my opinion]), but otherwise I think it's good as an easier expert.
+1, good luck!
Keep in mind, I am not an official map judge; take my review as that of a normal member of the community <3
