To make a 3 box comic strip for novel scenes, you need to be concise. Let's say you're doing it for a fantasy novel. In box one, show the hero getting a magical item or power. It could be a simple drawing of a wizard handing a glowing sword to the young hero. In box two, illustrate the hero facing a big challenge using that power or item, like fighting a huge dragon. And for box three, show the outcome, whether the hero defeats the dragon and is celebrated or has to face new consequences.
Well, start by reading the novel carefully to understand the flow of the story. When selecting the scenes for the 3 - box comic strip, pick ones that can tell a mini - story on their own. For the first box, you might focus on the introduction of a main conflict or character. In the second box, show the development of that conflict, maybe a struggle or a decision. In the third box, resolve the situation in some way, like a character achieving a goal or a mystery being solved.
First, choose three important scenes from the novel. Then, for each box, sketch out the key elements of that scene like the characters and the setting. For example, if it's a mystery novel, in the first box show the detective arriving at the crime scene, looking around curiously. Next, in the second box, draw the detective finding a crucial clue. And in the last box, depict the detective confronting the suspect with the evidence.
