Draw the simplest things first, such as apples, pears, watermelons, etc. . Then the painter painted bowls, bottles, chairs and other furniture, and then painted more complex combinations of fruits (still life) and landscape paintings. (All sketches)
These have been practiced for some time. After I have some foundation, I will draw a plaster head, then a real head, and then draw the whole body.
You can also practice sketching at the same time, that is, draw a person or an animal for ten minutes. This is to train your ability to quickly grasp the general image of an object. Start drawing people who are still, and then you can slowly draw people who are moving.
You can also learn color painting (gouache, watercolor, oil painting) in the future, and you also need teaching materials to guide your study.
If you don't plan to learn better, just draw casually and draw whatever you want.
