Ulco, you and your 2 suns tricks!
Why not just reduce Highlight Intensity in the Water Shader/Reflective Shader? Much easier and more correct.
Bob, this is looking like a very nice image in the making. I agree the GI is a bit too high. I would say maybe try Strength on Surfaces at 2, instead of 5, so you get the accentuated surface lighting, but it's not quite so "glowy". You might also play with the GI Surface Details settings at higher values.
My main question is, are there bushes on the distant hills? If not, maybe use some simple objects with the same texturing or colors, if you're trying to save memory (TG can easily instance millions of bushes onto those mountains if you have enough RAM).
