I would prefer the first (0925) maybe with a tiny bit more fill-in on 
the right. The other one is a bit too flat to me. Also, I am not too 
sure about the dof in that case. Too extreme for my taste.

Are you kidding?
To me, skin is the only thing that really *needs* subsurface scattering,
especially on the face, which is one of the targets the human eye has been most
used and adjusted to scrutinize on earth under various lighting conditions.
Very nice procedural iris, considering it is an even more demanding challenge in
that respect. Do you mind if I use this Iris texture for the sample texture on
the blender to POV  exporter WIKI? or if I have to adapt it as a basis for that.


Faster SSS would be more than awsome, actually a grail for attracting animation
focused users along with motion blur.

I remember reading a good article in GPU gems:

Surprisingly enough, the first one uses a HDR light probe of an overcast 
sky (albeit in a park with some trees around, so there is /some/ 
uniformity to the illumination), while the latter one uses a light probe 
of a clear sky. (I suspect the creator of the probe didn't include a 
shot with a short enough exposure time to capture the true brightness of 
the sun; I'll try again with an added light.)

I guess you're right. Then again, the acceptable dof might also depend 
on how detailed the background is.

The darker one (2013-08-07 0925), definitely.

It is mostly the out-of-focus part of the figure itself that I question. 
With a more detailed background, I would prefer the figure to be sharp 
front to back, or maybe only a little out of focus in the farthest part.

(BTW, yes, I know the illumination is too greenish.)

Yes, I love this one. To answer your second message, the 'greenish' 
illumination has a real function here I believe. It enhances the red hear.

As for me, this would be final.

It’s one of those images that are worth looking at, as you would look 
deeply into a painting.
The hair bothers me but she is Elvin so she doesn’t follow the rules. ;-)
The eyebrows need reddened to match hair, though.
