I see you reverted back to your big resolution rendering
I still think the lower resolution with the somewhat ridiculous AA looks a lot better, especially on the bushes (in the background).
That's a personal thing of course

This cubic b-spline filter together with that crazy AA still gives sharp images, but with that natural looking softness. I think I love it

lol
The softshadows really add something extra, though the new brighter lighting makes the shadows themselves a lot brighter and thus the soft shadow benefits are somewhat lost. See where I'm going?
How did you hook up Frank's crack shader into your network? There seems to be a conflict somewhere because you have some facetted faces.
I hope you consider my suggestions constructive and not as me being negative

Cheers,
Martin
