As digital illustration becomes more widespread, the number of self-taught illustrators who produce “Doujinshi (self-published print works)” and post pictures on social media has increased. However, the drawing method used differs depending on the situation, and it is not easy to learn by oneself. It is essential to observe a model closely when drawing, but it may not be feasible for beginners to do it alone. We, therefore, propose an observation method to enhance the beginners’ awareness. By verbalizing the features that beginners are not aware of, our approach enables them to make thorough observations independently. We conducted an experimental test to clarify the effects of verbalization for observations and copy-drawings. Then, we found that the proposed method of encouraging verbalization enhanced observations for many beginners and facilitated illustration copy-drawing.
