Start with basic shapes and simple lines. Then, add details and shading gradually. Pay attention to proportions and perspectives.
First, sketch the outline roughly. Next, focus on the characters' features and expressions. After that, work on the background and colors for a complete look. Remember to practice regularly to improve your skills.
To draw comic book style step by step, begin by imagining the scene or character in your mind. Make light pencil sketches to outline the main elements. Add darker lines for definition and use different tones for shading and highlighting. Keep experimenting and having fun!
