Jeonghyun Seok

Hello, I'm illustrator Jeonghyun Seok.
Besides my work in creating
Marvel cover illustrations, music videos,
broadcast network videos, and various
other video productions, I’ve also authored
the “Stonehouse’s Anatomy Note.”
This 650-page figure drawing textbook
took me 9 years to write and is now dubbed
THE textbook of figure drawing.

A well-drawn human body doesn't just use
simple anatomical drawing techniques;
it requires a strong grasp of how the body flows.

I want to give you insights on how to bring
planned concepts to life by sharing techniques for
sketching, expressing the flow of the human body,
and even creating backgrounds.

Background images
Are there any standards and/or rules you've set while drawing illustrations?

There's this thing called the "Pygmalion effect." It's a psychological phenomenon stemming from the mythology of a sculptor who had fallen in love with his work. Instead of taking it simply as a far-fetched and unrealistic myth, I believe it should be the goal for every artist that creates tangible artwork. Therefore, like the sculptor in the story, my primary goal is to be satisfied with my work first before satisfying others, and for that to happen, one must ceaselessly explore, study their work, and train their skills.

What core knowledge
can I gain from this class?

What I struggled with and worried about the most as an aspiring artist was the basic understanding of drawing and aspects of the human body. I taught myself to draw by simply copying the works of famous artists, but those drawings always came out looking awkward and unsatisfactory. I think this thirst for growth drove me to major in fine art and commercial art respectively for over 10 years. After graduating, I worked as a lecturer and realized that there were many students with similar struggles. This inspired me to write my book Stonehouse's Anatomy Note. I learned and felt a lot of emotions while writing it. I'm sure that sharing the trials, errors, and insights I have acquired through this process will be very helpful to my students.

What is the most important factor I need to consider when drawing a human figure?

When drawing real people, it is vital to capture more than just their outer appearance. You must be able to express their personality and overall impression through your work. To do that, you should try to meet various people to observe different lifestyles and behaviors. These experiences will serve as ingredients for adding life to your character drawings. Even if your drawings seem to lack something, there's no need to despair because drawing is a way of expressing the values and different perspectives one may have when looking at a subject. So you should have faith in the aspects you're good at and maintain an attitude of continuously seeking gradual improvement.

What will students learn
from taking this class?

First, learn how to create a character by understanding the structure of the human body. The body consists of countless visual characteristics, so it's important to know which you need to observe and emphasize. Next, learn the basics of drawing and sketching realistic characters. To create the illusion of real objects within a static scene requires a basic understanding of movement, light, and the depiction of three-dimensional objects within a given space. Lastly, I want you to gain confidence in your character art. My insights will help you strengthen your skills through in-class practice and a step-by-step lecture experience, giving you the confidence and motivation you'll need as an artist.
