Through induction, the picture is integrated. Only by integrating observation and performance can the picture be atmospheric.

The relationship between reality and reality is a kind of ability or characteristic of visual innate existence. When we observe objects, our vision will naturally pay attention to those parts with large contrast between light and dark, and the rest will naturally weaken. This form has great advantages for the expression of space.

Second, using "brain" painting can prevent plagiarism.

"Copying the object" is simply copying the details and colors of the surface of the object with a pen passively, locally, without thinking and without any emotion. I don't know what kind of problem I want to solve, it's just a pipe dream. The most extreme examples are those pictures that are portrayed everywhere, regardless of truth or falsehood. This kind of people mistakenly understand "painting well" as "painting carefully". The more they want to "paint carefully", the more they copy the surface of the object, forming a vicious circle and becoming a "stupid painting" without thinking. In addition, there is no "flatness" in volume and space, no "chaos" in contrast between light and shade, and "scattering" in shape, which may also be the "bad consequences" of plagiarism.

This "evil result" mainly comes from the mistakes of consciousness in the mind and the superficial and conceptual observation. Art comes from life and is higher than life, because art can't and doesn't need to copy objective objects like photos. It needs to be integrated into your emotions and feelings, your understanding and handling. Therefore, in the process of painting, we should choose, refine and summarize according to the actual situation.

Sketch, a painting modeling language, is mainly the visual transformation process of three-dimensional images in the picture. We should always remind ourselves that it is a real entity. Mastering the sense of square shape means that you have traveled in the ocean of art.

Third, in order to fully grasp the shaping of the avatar, these courses must be purposefully trained.

Face, side, three-quarters side and angle training such as looking up, looking up and looking down should be practiced more and cannot be ignored.

1. The front of the portrait

The above picture shows the front corner, with complex light and top light. The face and neck on the right side of the figure are in darkness, which is also the difficulty of this painting. Because the light is sideways, it is easy to pull the front and side of the face apart. But the author has a strong sense of cube, which opens this relationship well.

2. The profile of the portrait

When drawing a profile, we must grasp the dividing line between light and shade from the temple line to the cheekbone to the chin head, and establish the physical relationship between the front and the side of the head.

When we draw the head portrait in the front corner, the facial features are closest to us, and the ears and neck are relatively backward. When we show the profile head, our ears are closest to us. Of course, it is important to describe the five senses, whether it is front or side. In addition, we can also learn from the expression of head shape integrity from forehead to top of head, the space from cheekbones to nose, and the expression of texture with distributed pens.

This painting is obviously sideways, with ears in front, cheekbones in the back, cheekbones in front of eyes and eyes in front of nasal roots, which means that the eyes will have a certain shape that intersects with the eyebrow arch and nasal roots, which is the key to expressing space. If you draw the front, you can see both the distant eyes and the distant nasal roots, so the shape will be particularly thin, and it is not convenient to express space because of the lack of shelter between the shape and the shape. Therefore, it is also necessary to pay attention to choosing the angle of side painting.

From this perspective, the ear must be emphasized. The author draws the modeling features of the ear without any concept at all, and reflects the image features of the characters themselves in place, including cochlea, helix and earlobe, which are well explained, that is, the painting is loose and the content is clearly explained at the same time.

3. Three quarters of the profile of the portrait

The author of this painting clearly distinguishes the front, side, bottom and top of the head, and has a strong sense of body. Then, the color of the face is relatively inclusive and more transparent. On this basis, taking the five senses as the center, we can see that the performance of the five senses is very delicate, and the strength of the five senses is very wonderful compared with the strength of the face. This primary and secondary relationship has a very open rhythm, which is also a result of the author's subjective consciousness. Judging from the performance of the whole picture, it is very detailed.

After the clothes are finished with a pen, the graininess of the pen is basically maintained, without too much friction, and a rough texture and a delicate skin texture are formed, which are also very different in rhythm. Judging from the relationship between black, white and gray in the whole picture, because the hair color of the characters is relatively light, if the character's collar is painted white, the picture will appear slightly floating, so the author chooses the collar with relatively heavy color. It just forms a rhythmic contrast with the white above. Then on this basis, we will grasp the wonderful characteristics of the five senses.

At this stage, grasping the overall situation is the core. Can you really form a whole observation object and a sense of control over the picture in your mind? Do you know exactly what the result of your painting is? These are all questions that we need to think about. We should not draw all the details of the dark parts before subtraction, but think about how to refine a picture and how to choose a picture before drawing. This is the most critical place. Only with this overall consciousness, your picture will not lack a sense of volume.
