[Quality, Production, Composition]
- Style: Vintage pop art illustration characterized by dot (halftone) textures and strong black outlines, like the style of Roy Lichtenstein or American comics.
- Subject: A product drawn as if it were jumping out vigorously in the center. Radial lines (focus lines) spread from behind the product, enhancing the sense of dynamism.
- Typography and Speech Bubbles (for GPT-image / Nano Banana Pro): The onomatopoeia BOOM!! is drawn in large, powerful, 3D colorful comic-style letters, and the text Awesome! is placed inside a classic speech balloon. A banner for Ultra-lightweight, High Volume! Latest Portable Speaker is designed at the top of the screen.
- Color/Tone: Vivid and high-contrast pop art colors such as yellow, red, blue, and black.

[Strict Layout and Output Constraints (Required)]

- Prohibitions: Photos of the finished poster in a frame, photos pinned to a wall, mockup photos placed on a desk or paper, perspective distortion of paper edges, or drop shadows.

Absolutely NO photo-of-a-poster mockups: no picture frames, no poster-on-wall or poster-on-desk shots, no perspective warp or drop shadow around the artwork's edges.
