Sketch is an important form of personal artistic ability, and it is also an important means of personal collection, thinking display and creative construction. Let me briefly talk about the specific steps of sketching. Observation is to look at what you want to express, whether it is people or scenery, and the scope you want to express. Composition, if it is a character, depends on the proportion of your paper and the character you want to show, whether it is the whole body or the bust. Scenery is about the size and location of the theme you want to express, as well as the location and size of other environments. Shaping means having a plan and starting to write. The key step is to emphasize the proportional relationship and position between objects. In-depth, in-depth is to continuously strengthen the light and shadow and modeling after the completion of the large frame and proportion, so that the overall sense of the picture is stronger. The ending is the overall adjustment of the picture, as well as the signature and date. After this, a sketch is basically completed.
