WIP Tips - what should I improve? Map preview in topic.

Here is the map.
Couple of things before you have a look at it;
-its mostly unfinished
-sector outlines are a rough sketch at best, but you can probably guess what I was aiming at
-I may have used too many texture layers, but I was trying to make the map aesthetically pleasing, before I gave up on it, realizing there is probably too many mistakes
-I have not finished placing most of the cover
-It is quite hilly on purpose, with a lot of narrow flanking routes for infantry
-Lots of water, also on purpose
-It was supposed to be a 1v1 map, but I have realised it is too big in the middle of making it. Its kind of hard to judge the size you want, when creating it. It could probably be made into a 2v2 map instead.
-I have tried to make it semi-symmetric
-I have separated spline layers neatly for easy manipulation
-Only few splats placed
-In the middle of making it I have decided for the river through the hill

Thats about it. If you have questions just ask, im mostly looking for tips before I try to make an actual postable map for Workshop. I learned most of the WB basics while creating this, so this is not something I wanna finish and you are free to use it if you would want to.
