I like it a lot but it seems more of a sketchy effect than hard, dramatic 
light.  There is more noise around the face than I see in the Dave Hill 
examples.  I think what you need is more contrast, more color saturation and 
more shininess, whatever that is in computer graphics terminology.  I 
haven't tried to work with the photo to try to get these results.  Good 
work, Trev.
