How does character design typically differ between Western comic book art and Japanese manga art?

Western comic book characters often feature more exaggerated anatomy, emphasizing musculature and heroic proportions. Facial features tend to be more realistically proportioned, though still stylized. Manga characters are known for their large, expressive eyes, simplified noses and mouths, and a greater emphasis on conveying emotion through facial expressions. Body proportions can be more varied, ranging from realistic to highly stylized 'chibi' forms.
