I'm currently using AI model to draw my characters.
There're tons of Photoshop work involving in and it forced me to learn how to draw the hands, facial expression and all subtle things AI cannot draw. How funny that it is AI arts making me learn how to draw something for the first time of my life.
It's just a free game for hobby so I'll not hire any real artist. But hell if there's a day I can open a kick-start to collect some budget, I need a real artist simply because AI drawing is extremely frustrating when you want to be very, very specific.
I'll say even if there's AI, a real artist can use them million better than untrained layman, and YES you can see the difference.
