I think the pursuit of realism is a noble goal with Poser, since it makes the rendered image more agreeable to our eye, and thus enhances it's "artiness".  A poser render with nostril glow, poke-thru's and no shadows is not going to look that appealing, whereas something that is well put together has the potential to be very appealing to look at.
