Well, I didn't pay very much attention to final adjustments, just quickly changed the quite dull lighting in Irfanview. In PS I would have done it better perhaps. I have saved an exr, so I'll check it out properly. There are no fill lights, just a very cloud filled sky, increased exposure in camera (1.4) and GI 2/2. I think with less 'normal' sunlight and a few soft shadowed fill lights, I could have produced more soft shadows under the objects. Might do a crop to try it out, but I'm eager to go to the next.....
By the way, here's an in between little test, which I will not pursue at this moment. I warn you, quite ugly...
