Well, to write a good comics script, you need to focus on visual storytelling. Plan the page layouts, think about the flow of action from panel to panel. Also, pay attention to character expressions and body language to convey emotions without relying too much on words.
Start by having a clear story idea. Outline the plot, characters, and their arcs. Then break it down into scenes and panels. Make sure the dialogue is engaging and the visuals are easy to imagine.
First off, know your audience. Understand what kind of story and style will appeal to them. Then, build interesting characters with distinct personalities. Develop a compelling plot with twists and turns. And don't forget to leave room for the artist's creativity in interpreting your script visually.
