Contagion forge map thread

So I finished the map I was working on called Contagion, its essentially a citadel map remake from halo 3 but I added a twist by adding flood particles to the map and infected looking areas. I would like some feedback from anybody willing to take a look at this map, it took me 9 hours to build over the course of 2 days and is my second complete forge map, it supports 2v2, 4v4, CTF, strongolds and FFA up to 16 players.
Heres a video link to a preview of the map: https://www.youtube.com/watch?v=P0Lx56yUxpE
But if you cant be bothered watching the video or you would like to see the stages of how this map was designed ive also included an imgur link to some screenshots of the map during and after its build completion: http://imgur.com/a/knf2X
