Everyone has their own way of drawing a cute character’s face, and even the same person might draw it differently depending on the character's hairstyle, the surrounding environment, or the angle of the face. Since there’s no definitive answer in drawing, I believe it's more important to develop a sense of what makes a face look pretty rather than establishing a theoretical method. However, when adding color, sometimes the flaws in the sketch of the face might get covered up. This can prevent the face from looking as beautiful as it could, so to avoid any unfortunate results, it's better to ensure the face looks pretty enough during the sketching stage.
In the coloring stage, rather than reflecting reality, I tried to reflect my own sense of how reality feels to me. If you look closely, you'll notice that the direction of the light and the color choices are somewhat disconnected from reality. Hipa and Sekoshi-chan's hair texture, the bright area between their chests, the sweat-drenched thighs, the soft skin expressed with an airbrush, the blush emphasized by contrasting saturation, the brightening around the arm joints, and the depiction of wet clothes—all of these are not simply direct representations of reality but rather a reconfiguration to emphasize or reconstruct only the parts I wanted to express.
In this way, because the direction I prefer becomes the answer, drawing is a difficult joy to give up.
