Thanks, But I think did very little work. All the magic is done by the backdrop. My work was just getting pose match perspective, some lights, and some tone mapping. With backdrop, rendering took 2 mins max. I would give all the credit to original image here:

I tried some methods and tinkered settings with Daz but came to the conclusion that its best done in the post because that backdrop has such tricky soft shadows if you look at the trees. I knew I would fail which is why I did it cause I want to see how far I can go. I will redo it tomorrow.
