wow nice work! - you should repost it in the modding section to get more feedback
You should use more light
Put some in the middle of the room as if you would have some light comming from a lamp or something. Also did you try to use a region trigger to hide water plans etc? Would be also intersting to see AIGrid you could raise the terrain from one side so it gives the impression the ship sinks and maybe add a really nice tactical aspect to the map (range att bonus etc)
