I Know I Should Practice Body Structure, But...
Have you ever had this experience while drawing? You finish a figure painting, your heart is full, and you can't wait to share it — so you post it online. And then you're met with merciless fire like this:
Under that kind of bombardment, you often end up completely deflated, not wanting to draw the next picture at all.
Of course, when we put work online, we'll inevitably run into some sharp-tongued, impatient attacks. But if we understand structure practice more deeply, we can avoid much of this unnecessary grief when we draw.
Which raises the next question: how exactly do you practice? Today, let's talk about a few key points beginners must know when practicing body structure.
Break the Body into Geometric Forms
At the beginner stage, to understand how to draw the human body, I recommend starting with a completely still, upright pose like this. In this exercise, we usually take one head length as the basic unit of measurement for the figure. Measuring the whole body this way, the relationships between limbs can be pinned down clearly through comparison. For example, counting down four head lengths from the top of the head lines up with the lower edge of the pelvis; and the tenth rib — the lowest edge of the ribcage — sits just slightly above the elbow when the arm hangs down... and so on. All of these can be found by comparing one landmark against another.
Once I understand the body's basic proportional relationships, when drawing the figure I usually think of it as a set of much simpler objects.
For example, the head: the upper part of the skull can be understood as a sphere, and the chest and ribcage as a halved coffee bean. Deconstructing the body this way, drawing a static figure is no longer a problem. But what makes the human body so captivating is its dynamic beauty — so when the body moves, how do we capture that sense of space on paper? That brings us to the second key point: treat the body as transparent.
Treat the Body as Transparent
You've probably seen a transparent globe like this. When drawing the figure, I often view the body the same way — as a transparent object crossed by many lines of latitude and longitude.
This is the built-in mannequin system in Clip Studio — by rotating it and switching camera angles, it helps us understand the body from every direction. A very convenient tool. Notice that this mannequin is covered with criss-crossing lines, just like the wireframe globe we mentioned. On this "globe of the body," two kinds of lines are essential to know: the centerline and the cross-section contour line. These two invisible lines help us judge, on a flat surface, how the limbs and body are rotating. In the example above, reading the figure from left to right feels like watching the head turn toward its right side, and you can see the head's centerline gradually shifting toward the figure's right as it turns. So we can use the centerline's position to judge a figure's horizontal rotation. And the differences in rotation between the head, chest, and pelvis — the body's three great masses — are a major key to the torso's dynamism when we draw figures.
Cross-section contour lines are guide lines expressing a limb's cross sections — a crucial concept for conveying limb perspective. In the image above, the cross-section lines act like a knife slicing the arm into four pieces. After slicing, try rotating the arm upward: the higher it lifts, the more the section lines curve upward. From this observation we learn that when an arm rises above our eye level, its section lines form upward-bending parabolas; conversely, when a section line sits below our eye level, it curves like a smile. With the centerline and cross-section contours as aids, sketching the sense of limbs receding or projecting in space on flat paper becomes much easier.
Compare Landmarks Against Each Other for Placement
When drawing people, every part of the body can serve as a reference point. Take the image above: while doing a study, green lines like these appear in our mind to help us find positions — dropping a vertical from the forehead lands about where on the collarbone; angling outward from the forehead at roughly what slope lines up with the shoulder peak... and so on. These lines don't exist in space, but we can draw these nonexistent lines ourselves to accurately locate each part of the subject. So to learn body structure, beyond theory, training your observation matters greatly. Sharpening your sense of what to observe while drawing is, I think, one of the biggest keys to doing studies well.
Those are the key points I believe beginners should note when learning body structure.

That's it for these structure-learning tips for beginners — thank you, everyone!
