First buy some essential basic books, including human body structure, facial structure, still life description, figure sketch and other basic books. Don't start copying after you get these books. You must first see the direction of the structure, how to use the pen flexibly, the order and weight of the arrangement.

Secondly, generally speaking, the order of sketch practice should be geometric plaster, still life, skeleton, plaster head, real copy and real sketch, all of which are gradual transitions. It is necessary to lay a solid foundation for a stable painting style in the future.

Third, at the beginning, you can carefully arrange the cables on the back of the paper with a pencil, which is a hot hand before painting. The cable should be even and smooth, the two ends of the wire should be light, the middle should be heavy, and the spacing between wires should be even and natural.

Fourth, understand the basic five tones of sketch, which will be mentioned in the basic book and observed by yourself.

Fifth, understand the relationship between point, line and surface and the texture on the picture, and how those painters use this 3 yuan to set off the picture.

Sixth, a good sketch can always find the shadows of the basic five tones, and there is the use of black and white gray, which is divided into light gray and dark gray.

Seventh, at least find someone who knows how to paint to help you look at it regularly, so as not to take too many detours. It may not be in tune at first, but at least the lines should be straight and the shape should be accurate. This is the most basic requirement for painting.

Eighth, the rest is empty talk. From now on, use strokes.
