First, brainstorm ideas. Write down all the possible story ideas, no matter how crazy they seem at first. Then, narrow it down to the one that has the most potential. After that, start building your world. Decide on the setting, whether it's a bustling city or a far - off planet. Then, work on the character arcs. Each character should grow and change throughout the story. And finally, revise your work. Read it over and over again, looking for areas to improve, such as making the dialogue snappier or clarifying a confusing plot point.
A major step in writing a graphic novel is to create engaging characters. Develop their relationships with each other. Are they friends, enemies, or something in between? You can also use symbols and motifs throughout the story. For example, a recurring flower could represent hope or love. Also, when it comes to the layout, think about how the panels will flow from one to another. Will they be arranged in a traditional grid or in a more experimental way? This affects how the reader experiences the story.
