In fact, the name of college art is a bit big, which is not much different from junior high school and senior high school, including sketch, color and sketch. Generally speaking, sketching and sketching are basic courses, which are purely hands-on and have nothing to do with design and composition. As an art student, I know a little about these things. In fact, what I learned in college is similar, and there is nothing too special about art. It is one thing to draw more and practice more, followed by practicing your eyes. There is a saying that "the eye is superior but the eye is inferior", which is about your appreciation and understanding of works. If you can appreciate and understand the author's ideas, you can draw the same thing. As for how well you can draw, it depends on how deep your hands are. Copying is a shortcut to improve skills, but we should not rely too much on it, otherwise it will not have its own characteristics.
