Well, to draw simple comic faces, focus on exaggerating certain features for expression. Like big eyes for a cute look or a wide smile. Also, keep the lines clean and simple. Practice different expressions to get the hang of it.
For simple comic face drawing, begin by sketching the outline lightly. Pay attention to the proportions of the features. Add details gradually and don't worry about being perfect. Have fun with it and experiment with different styles.
Start with basic shapes like circles for the head and ovals for the eyes. Then add simple features like a nose and mouth. Use light strokes to outline at first.
