Good video, shakenbake. I like how much consideration you have given to flanking routes and chokepoints in this map. It's nice to see a night time map that is actually dark.
One thing which stands out in the map, though, is how "pointy" the terrain is. Do you plan to increase the tesselation in the future? It's kinda jarring to look at, and looks like something taken out of a 2004 game. Also, the straight cliffs which stand in a square around the perimeter of the map are quite noticeable and seem unnatural. If you can afford to give up some performance, I would level some of those out and add a forest region that goes out into the distance with a spawn protection volume to stop troops from straying too far.
Overall though, the map has quite a lot of detail that isn't present in other custom maps, and the layout looks quite fun. I look forward to playing it.
