Yes, there is something wrong with the ear and it seems to me there is 
no SSS happening at all. I might have messed something up with the uv- 
mapping and will check this out.


> But why not pov's new SSS feature?

This was my first idea, but it is in an early alpha stage and not 
working for anything that is more complicated than a simple wax candle 
and a point light. E.g. it does not work if *any* partially or fully 
transparent textured object is involved (like the hair, eyebrows and 
eyelids within this image). It also does not work when the light-source 
does contain a looks_like statement or the SSS object multi-layered 
textures.


> Hair could get a bit of an overhaul.

I'm quite satisfied with the hair and I tell you why: within almost all 
images from the "pros" I've seen so far the hair is either completely 
cut & paste from a real photo or at least heavily post-processed within 
photoshop.
I'm not a POV purist but I would like to have the hair rendered within 
POV-Ray and for what I see there are just two minor problems, the 
transparency map needs a bit more work at the forehead and the 
bangs/strands should be formed like a cross and not be just a plane (if 
you know what I mean) and both issues are quite easy to solve.

Sure, but this is not a "beauty-shot", its only a skin test and not much 
more. The Chinese room and its lighting was already made for the TINA 
CHeP competition at
http://www.tc-rtc.co.uk/
and I simply did put the poser girl into various interior scenes I have 
done over the years to see how realistic the skin will look under 
different lighting conditions without adjusting anything else. In this 
case it just happened that there is just a wall paneled with almost 
black wood to be reflected in the eyes and this is the most unfortunate 
object to create a lively reflection ;)

thanks for the input
