If you're worried about job opportunities, I'd recommend to have a shift in your artistic approach. Don't make people want your 3D models because they're technically good, but because they say something about your insane mind.
Be the reason why people want to commission you, where no matter if a person or machine can recreate your technical style 1.1, people just want to know what you come up with.
