That toxic texture is hideous
I was gonna wait till I'm mostly done, but would you recommend doing lighting earlier?
Type "buildcubemaps" into the console, sometimes cubemaps do funky things and don't work correctly from the start.
The lack of dynamic lighting in the map suggests a leak, has the displacement the water is in got a brush beneath it? Displacements do not plug leaks, you need a brush beneath them.
