I don't do art, so you can take this with a grain of salt. I saw a video by a guy that was about his art style. He went from a very skilled realistic art style to a simple cartoon style. He was saying that while it's important to get the fundamentals down, it's also important that art is about expressing oneself. If it becomes about trying to make something look better and better, it sometimes becomes less about an expression of yourself and a connection with other people, which is the whole point of art. Edit: Much later. I saw this video about the basic mistakes of beginners, but she really means everyone. She talks about knowing your tools, practicing enough, using references, comparing yourself to others and not learning the fundamentals. She has tutorials on the fundamentals. She also commented about viewing the art of others. Something I learned recently is that professional artists use references. I didn't realize that.
