The first stage: cultivate interest, usually boring to draw and play, at this time, we should look at more pictures and gradually improve the aesthetic.
The second stage: cultivate interest and start copying some pictures you like, or cartoon characters. At first, you will find that your paintings are not bad. After a while, you will think that your previous paintings are rubbish. At this time, your aesthetic has improved a little, and you are aware of your own shortcomings.
The third stage: entering the learning period, I began to look for tutorials online, but I didn't know which videos to watch, so I could only learn some scattered knowledge points. This stage takes a long time. Keep painting, and you will find that you have really improved, copying more than before, but originality is still bullshit.
The fourth stage: start some targeted learning, understand your own shortcomings, and finally start effective replication. From my own paintings, I can see what is not good, the originality is better than before, and I have begun to have a sense of composition and so on. You began to be good at drawing some big faces or eyes. At this time, you entered the old-fashioned thinking and felt that you were making rapid progress, so you stopped studying, stayed in the comfort zone and started your own painting career.
