That's because the position of your five senses is a bit wrong, your face is not well grasped and your painting is thin. The left eye is too far to the left, and the shape of the eye is a bit wrong. The highlight of the model is very bright, so it is suggested not to adjust the bullet too deeply at first. As for how to grasp the proportion of character characteristics, we can use it flexibly according to "three courts and five eyes", because the model we see is in different positions, and her proportion of "three courts and five eyes" is also different. It is recommended to observe carefully when drawing, don't be stingy with the lines, and experiment many times until the position of the five senses is accurate. After the facial features are determined, the face shape and the tone of each position are basically determined. All of the above are theoretical things. In fact, we have been told to practice before the exam. Painting is actually cloning some things in the album in the form of graphics. Because of this, there is also a simple way of sketching. You can find some transparent white paper first, then some pictures of people, and then "paint red" first. When it reaches a certain number, your above problems should be solved. It may sound like practicing calligraphy, first "draw red", then "copy" and so on. In fact, every Chinese font is like a painting, and the sketch we learn is actually "advanced copying". Actually, I still practice more, practice more. There are more pictures stored in my mind, so I have a position in my hand, and the proportion of each place is unconsciously found. All right! Too much talking at once. I can't help it I can't stop talking about painting. Hehe, I wish you a good sketch, hehe!
