Eyebrow arch, nose and cleft palate can be regarded as three horizontal lines, and the centers of eyebrow, human and mandibular tip can be regarded as vertical to the central axis of this group of horizontal lines, which together with * * * constitute the dynamic line of the head, and the dynamic characteristics can be observed and grasped through their perspective changes in motion.

Eyebrow arch, nose and cleft palate can be regarded as three horizontal lines, and the centers of eyebrow, human and mandibular tip can be regarded as vertical to the central axis of this group of horizontal lines, which together constitute the dynamic line of the head.

Different tools are related to the nature and composition of sketch, and tools will also affect the painter's mood and skills.

Charcoal pen can be used for both.

From the size of the work, large-scale sketch works are suitable for drawing with charcoal pen, and the outline and carefulness can be carefully studied and analyzed for a long time. As for pencils, they are suitable for smaller sizes. There are few large pencils, while pen-and-ink drawings are even smaller, and they are often used for illustrations.

The monochrome performance of sketch makes the tool very random, and it can often be used comprehensively to create a variety of picture effects, so it is a very broad world.
