SnowSultan explains all about lighting. See link. Personally I'm one of the minority who think ultra-realism is over rated. If you want ultra-realism, then take photographs, is the common argument and I see much rationale in that. It makes no sense to me that people want to do fairies and then complain that they don't look realistic. Why should they? What's wrong with the fantastic looking fantastical? Poser lets us go beyond reality...that's much more the point for me. But I'm always out of step. I've even gotten used to it.
