Haha, I totally agree with your critique, thanks.
I wasted ages f*cking with that fog, its saturation, color, density, blah, blah, blah. Tried hand-painting it, tried using a Z-depth pass on the base render as a mask for the fog...
Finally, I decided I should just leave it alone, and maybe the solution would magically appear to me later.
I may just do a version that fades to black in the distance, or something.
