Like I said, other Vue'ers have different opinions... :-) Chipp has recomendations very different from my own. Important thing is that you experiment and decide for yourself.
Just some remarks from my side:

Chipp quote - "Paul, next in the Fog and Haze tab, there's a quality boost setting which should be pretty high as well, to remove the noise from the light rays."

I would say this is not necessary in your case. I dont see any noise in your rays.

Regarding Chipp's choice of GA, as opposed to GI, I would disagree because those subtle shading effects of GI can be noticeable from afar, depending on the image.

Chipp quote - *"soften the sunlight to something like 5. "
*Be warned that this will increase your render times dramatically. Furthermore, if the sun is volumetric and you do this, Vue many times (always?) automatically changes the shadow from ray trace to shadow map. This renders much faster but I personally hate shadows generated this way. I recommend that you go to sunlight settings (shadow tab) and disable shadow map (and improve the quality to 1 or above).

P.S.: Like Chipp, I also do not like your avatar at all because it seems directed to all of us here.
