Render times are bad of course. For smaller images it might not so problematic.
The image that i am rendering with soft shadows the second time, takes longer then i expected. 66 hours and still rendering.
I used soft shadow values that are much higher(3 times higher) then the default ones.
So i should not be so much surprised in that aspect probably.
A different texture look is out of my reach with these render times. But i might try it in standard images later.
