The main difference is that a graphic novel is usually a self-contained story with a more complex plot and character development. Illustrated novels, on the other hand, often have more text and the illustrations mainly support the text.
The key distinction lies in the balance between text and images. Graphic novels have a greater emphasis on the visual aspect and can stand alone as a complete story. Illustrated novels have more text-driven storytelling, with illustrations adding to the atmosphere and helping the reader's imagination. Another difference is that the art style in graphic novels is often more detailed and stylized to convey the mood and themes.
Well, a graphic novel typically has a longer and more continuous narrative, with the images and text working together to tell the story. In an illustrated novel, the text is still the main focus and the illustrations are more like enhancements. Also, graphic novels often target a more mature audience compared to illustrated novels, which are often aimed at younger readers.
