Having dabbled in 3D a few years back I can say at the time it seemed there was a certain amount of disdain toward it, unless of course you were a known comic artist and then suddenly it was no problem to get published no matter how bad your work was (Marvel's "Spiderman: Real Life" anyone?). 3D isn't easy, with the artist generally having to design/build/light the set and model prior to rendering (premade models and sets are of course available online, too). However, it's still a niche. You can't replace working with a real model. Granted it's a heck of a lot easier - the model's always available (not to mention on time), poses exactly as you like and will hold the pose indefinitely. However, a real model contributes to the shoot via her unique character and personality and working together to achieve a stunning shot can be very rewarding. 3D's getting better and better, but in the end it's still only 3D.
