What are the primary visual differences between American comics and Japanese manga?

American comics typically feature a more realistic or exaggerated Western art style, often with a focus on detailed musculature and dynamic, sometimes hyper-realized, poses. Panel layouts can be more varied, and speech bubbles often have a distinct shape. Japanese manga, conversely, is characterized by a wide range of stylized art, from highly detailed and realistic to extremely abstract and cartoony. Key visual cues include expressive, often exaggerated eyes, distinct character designs, a focus on internal monologues, and a tendency to read panels from right to left, top to bottom.
