How to practice drawing lines and surfaces?

First, to draw a good sketch line, we should start with the most basic geometric shapes, such as rectangles and ellipses. Pay attention to the smooth and accurate writing of lines, and remember not to drag your feet when lines come into contact with paper, otherwise it is neither fish nor fowl. If there is something wrong with the line, you are afraid that it will not be straight.

Secondly, when sketch lines show complex pictures, the composition must be summarized and refined. Only when the composition starts from the whole can we grasp the whole picture and use the general line route to guide the subsequent sketch painting.

Third, when a single line represents a sketched object, the structure of the object and the line representation of the outer contour are also more important, and the internal literature and history can be appropriately blurred.

Fourth, the performance of sketch lines should be perspective, with thick near and thin far, big near and small far. When sketching, it is particularly important for lines to grasp perspective, which is the fatal point of line sketching, and accurate line perspective plays an irreplaceable role in the effect of the picture.

Fifth, the arrangement of lines is also an important aspect. Where there are many wrinkles, reasonable use of the arrangement of lines can create some light and shade, and the arrangement should be simple, smooth, accurate and certain. This arrangement can emphasize the generality of the whole picture, avoid the triviality of the sketch picture and achieve the perfection of the overall picture effect.

Sixth, sketching lines is not only the foundation, but also requires us to persevere. Control the written lines, learn more and draw more, and improve the sketch in line practice, instead of drawing rigid lines, go directly to actual combat, and then sum up the sketch lines and painting skills that suit you.
