Just downloaded this mod, and I'm impressed so far.
Just a small comment:
I'm on a calibrated, capable SDR display, and my initial thought was that it's a bit oversaturated. Especially my very first look at the mod, an overcast September morning. The oversaturation was milder as the day progressed, and especially as the sun came out. The oversaturation seems to be replaced by a haze, or overly bright weather. Again, this is based on a September day going from overcast to full sunny at around lunchtime.
I'll try to lower the saturation value in the XML, but is there a way to lower the midday haze or brightness a bit?
Edit: The haze is more pronounced from inside a vehicle, outside the oversaturation prevail as the day progress.
Edit2: Lowering the daytime saturation to 1.0 makes it look quite a bit better on my display.
