Self taught artist, and I learned by copying my favorite comic books and painters.
Went to art school and a significant part of my art history class dealt in remembering the name of art "movements" which is a veiled way of saying a period when everyone was copying each other. Then of course you learn about the influential artists who heavily borrowed from xyz. Another funny one is "revival" which just means "straight up copy"
This is why I have limited sympathy for the uproar about AI art. It's just cutting through the boring part.
