The Most Common Mistakes Made by Beginner Drawing Students – What Do We Observe During Classes?
Updated: Sep 28
The beginning of learning to draw rarely looks the way people imagine it, especially if they have previously drawn mainly by intuition. The problem is usually not a lack of “talent,” but rather the way we look at an object, plan our work, and transfer what we observe onto paper. During classes, it becomes clear that many beginners encounter similar difficulties, regardless of their age or previous experience with art.
It is worth becoming familiar with these difficulties because some mistakes can be corrected relatively quickly. This does not mean trying to avoid every unsuccessful line. Mistakes are a natural part of learning. What matters more is understanding why a drawing does not look the way we expected and what can be changed during the next attempt.
Drawing What We Know Instead of What We See
One of the first things we work on when learning to draw is observation. People have a natural tendency to simplify familiar objects. We know what an eye, a cup, a hand, or a chair looks like, so it is easy to reproduce a memorized symbol of the object instead of carefully analyzing the specific object in front of us.
Dlatego przed detalem warto ustalić większe elementy: położenie obiektów, ich wzajemne proporcje, główne kierunki oraz rozkład jasnych i ciemnych powierzchni. Na zajęciach korekta często polega właśnie na chwilowym odsunięciu uwagi od fragmentu, nad którym pracuje kursant, i spojrzeniu na całe płótno.
This is why observational exercises may initially seem slow. Their purpose, however, is not to produce an attractive picture as quickly as possible, but to gradually replace familiar visual shortcuts with conscious observation.
Why Is It Better Not to Start a Drawing with Details?
Beginners often like to start with the element they find most interesting. In a portrait, this may be the eyes; in a still life, a decorative pattern on a vessel; and in an architectural drawing, a window or a section of a façade.
The problem arises when a detail is carefully developed before the basic proportions of the entire composition have been established. A beautifully drawn eye will not help much if it is positioned too high or is too large in relation to the rest of the face.
A safer approach is to work in the opposite order. First, we establish the position of the object on the page, its overall proportions, and its main directions. We then divide the larger form into smaller sections and only later move on to details. This way, any corrections made at the beginning do not require rebuilding an almost finished drawing.
Proportions Need to Be Checked, Not Just Judged “By Eye”
This is one of those difficulties that can remain unnoticed for a long time. A person looks at the model, then at the paper, and feels that the individual elements are more or less in the correct positions. Only after some time does it become apparent that the entire form is too wide, one section is too long, or the distances between elements do not correspond to the object being observed.
Learning proportions is not simply about memorizing established rules. The ability to compare is much more important. How does the width of an object relate to its height? Where is its midpoint? What is the relationship between one section and another?
Questions like these gradually teach us how to control a drawing. Over time, measuring proportions becomes increasingly intuitive, but at the beginning, consciously checking them is extremely helpful.
Pressing Too Hard with the Pencil Makes It More Difficult to Correct the Structure
Strong pencil pressure creates a clear, visible line, which may make it seem more confident and decisive. At the same time, however, it makes structural corrections more difficult and causes the first, still uncertain decisions to become a dominant part of the drawing.
At the initial stage, it is better to use light construction lines. This makes it possible to adjust contours, correct proportions, and search for the right shape without leaving a heavy network of corrections on the paper.
The amount of pressure can gradually increase as the drawing develops. Not every line should have exactly the same intensity. Varying the strength of the line is one of the ways to create a sense of space and give a drawing its character.
An Outline Is Not Yet a Three-Dimensional Form
The next step is to move away from thinking only about the outline of an object. An object is not simply a flat shape surrounded by a line. It has volume, surfaces facing the light at different angles, and parts that are closer to or farther away from the viewer.
This is why we return to simple geometric forms during classes: spheres, cylinders, cubes, and cones. We do this not because they are particularly impressive subjects, but because they help students understand how three-dimensional space and form are constructed.
The same principle later becomes useful in more complex work. A head can be analyzed as a combination of three-dimensional forms, just like a hand, a jug, or an architectural element. Drawing then becomes less about randomly copying outlines and more about consciously constructing form.
Light and Shadow Require Observing Relationships
A beginner may know where a shadow is located without yet analyzing why it has a particular tonal value. As a result, all darker areas may be shaded in a similar way, causing the form to appear flat.
Understanding light and shadow requires observing relationships. We need to distinguish between illuminated areas, halftones, the object’s form shadow, and the cast shadow it creates on its surroundings. The lightest and darkest areas are also important because they provide reference points for evaluating all the other tonal values.
A simple question can help: is this area actually dark, or does it only appear dark compared with the surface next to it? Making these comparisons develops tonal sensitivity much more effectively than mechanically smudging graphite.
Why Can Constantly Using an Eraser Interfere with Learning?
An eraser is a drawing tool, but it can easily become an automatic response to every uncertain line. A beginner may draw a section, immediately erase it, draw it again, and then erase it once more. The process then becomes focused more on avoiding mistakes than on observation.
Not every construction line needs to be removed immediately. Sometimes it is worth leaving it in place until the correct solution has been found. This allows us to compare several alternatives and consciously choose the one that best corresponds to the object we are observing.
A drawing does not need to look clean at every stage. Clarity and order develop gradually.
Regular Practice Is More Important Than Trying to Create a Perfect Drawing
One of the most common questions beginners ask is how long they need to practise before they notice improvement. There is no single number of hours because the pace of learning depends on several factors, including regularity, the type of exercises being performed, and the ability to notice and correct one’s own mistakes.
A series of shorter, consciously executed sketches can be more valuable than spending many hours refining a single drawing without analyzing its proportions or structure. It is worth returning to simple subjects and observing whether it becomes easier to judge angles, notice incorrect proportions more quickly, and better understand the relationship between light and form.
Progress in drawing does not always mean that every new piece looks better than the previous one. A very important stage of development occurs when the learner begins to recognize problems independently. If they can say, “this axis is shifted,” “I lost the proportions here,” or “this shadow is too strong,” it means they are developing not only their manual skills but also the way they see.
