1, the relationship between composition and large proportion

Composition is a basic factor that directly affects people's sensory and visual feelings. The composition mentioned here is not the requirement of composition in general painting, but the requirement of the characteristics of art college entrance examination. First of all, we should consider how to make full use of space according to the size of the test paper (mostly eight quarts, at least a few quarts). Take octagonal sketch paper as an example. Octagonal sketch paper is originally small. If the examinee does not make full use of the paper size to express the sketching object, your test paper will be discounted in the intuitive visual experience. The main problem of college entrance examination is not to draw the sketch object too big, but to draw it too small, leaving more blank places on the sketch paper, so that the head of the character you draw is smaller and weaker than many other papers, which directly affects the overall sketch work.

In the composition, the side of the model's face facing the paper edge should be left blank. Candidates should also pay attention to the different requirements in the sketch exam, such as drawing a collar or shoulders, so as to determine the position of the lower part of the composition.

After the composition is initially drawn, it is necessary to determine the large proportion of the body. Candidates are most likely to have problems in this step. Whether the proportion is correct can basically be judged by the painter's intuition. Some candidates think it's okay to have eyes or nose one or two millimeters higher or one or two millimeters lower on the screen. Obviously, they found that the proportion was biased, and they thought that it was not a problem not to correct it, which damaged the whole character image. Even if you draw well, you still can't get high marks. This is the weight of the proportion in the college entrance examination scores.

The proportion of figure is mainly solved in the first stage of sketch, but it doesn't mean that the following steps don't have to be considered anymore. This is also a misunderstanding of the question of proportion. Whether in the stage of laying a big relationship or in-depth description, with the appearance of the picture effect, you will find some uncomfortable parts. You must not be lazy at this time. Found the problem, easy to correct. The best way to correct the proportion of mistakes is to draw the position you think is right first, and then erase the wrong part instead of looking for it.

2. Build an important relationship

The large-scale relationship is well handled, and the spread of large-scale relationship is an important link. Some candidates don't pay much attention to this step, and directly enter the depth description of the picture, which affects the progress of painting. The sketch exam usually takes three or four hours. In such a short time, to complete a more in-depth sketch assignment, only by roughly completing the big relationship of the picture will there be enough time for in-depth characterization.

The so-called "laying a big relationship" means that in a certain period of time, the space, shape and structure of the sketched object and the relationship between black, white and gray are generally processed on the screen. At this stage, candidates can properly wipe the lines with their hands under the guidance of the teacher to improve the progress. At the stage of in-depth characterization, it is very cautious to wipe the tone with your hands.

3, in-depth characterization

When the big relationship of the picture is handled, it enters the stage of in-depth description, including the handling of the internal skeleton structure of the avatar and the description of the detailed structure of the five senses.

We often see that some candidates work hard, but the picture is still not deep. The main reason for this problem is the lack of understanding of the anatomical structure of human skulls. Candidates should use their spare time to learn and understand the anatomical structure of the skull. When you face the model again, you can find the inner connection between bones and muscles in an intuitive and vivid feeling. When you spare no effort to describe this looming internal structure, your sketch will really go deep into it.

Another content of in-depth description is the concrete expression of the five senses of the avatar. Drawing facial features is not simply drawing eyes and eyebrows, but connecting eyebrows with orbital bone, and showing the eyebrows growing on orbital bone and eyes embedded in orbital bone in a spherical shape; For the performance of nose, we should pay attention to the understanding and description of the structure of nose root, bridge of nose, nose head and alar; Draw the mouth together with the mandibular and orbicularis oris muscles, and don't draw the nose and mouth in isolation. We can also improve our knowledge and understanding of the structure of the five senses by copying some excellent template paintings.

Step 4 clean up as a whole

Finally, set aside some time to clean up the whole picture, such as the relationship between hair and the dark side of the whole face; Whether the depth of eye socket, upper eyelid, nasal floor and mandibular floor is enough; How to grasp the gray tone and bright gray tone of the light receiving surface; The big thing is that the expression of space and form should be adjusted as a whole, so as to show great effects.
