I say let jerks like that continue to believe that crap about the purity of 3d modeling software. while they're struggling for days to complete an illustration, I'll tell the art director I can do it in hours and be able to change anything in the piece on the fly including the pose. and I doubt his will look any better. I had an art teacher who used projectors to transfer his photos to canvas for his illustrations, many of his students were horrified "that's cheeting!" they would say, "when you're doing a book cover a week come talk to me about cheeting" he would reply "an art director doesn't care if you use toilet paper to do a project they just want results, It's your eye they're hiring" Who cares what tool you use to create your art just create!
