How does the design of a speech bubble contribute to the overall visual style of a comic book?

The style of speech bubbles can be an integral part of a comic's overall visual aesthetic. Simple, clean lines contribute to a modern, minimalist feel. More ornate or stylized bubbles can enhance a vintage or fantastical aesthetic. The color palette used for bubbles can also reinforce the comic's mood and theme. Consistent bubble design across an entire comic helps establish a strong visual identity and reinforces the comic's style.
