Ok, here's something I tried yesterday~ Thanks to the info which alessimarco provided me, I set up the portrait scene and added the UE2 environment base only, then messed around with the shading rate, deciding on 4.00 (I think). Below is the render with no postwork.

 

I then converted this image to black & white and did some postworking~ You can see the finished image here: http://www.renderosity.com/mod/gallery/index.php?image_id=2312636&section_id=&genre_id=&np

I hope this will be helpful~ I'll do my best to return each time I stumble upon something =)
