Your problem Pumeco is that blaming the medium for what it lacks instead of tailor your talent to use the medium. For instance, same picture you show of the girl in the shower. What if you sculpted her in stone taking a shower. How do you show the water in stone? Would you not call it real art? Or would curse the sculpting companies that made the tools to sculpt with. OR would find some other way to show the water, like actually using water or a  crystaline type of rock?

I think of Poser and CG art as a lot like Green Lantern's ring.  It's only real weakness is the color yellow.  But the only real limitation is your imagination.
