A vibrant pop-art style stylized portrait of a scuba diver, captured from the chest up in a bold illustrative aesthetic. The subject features clean, thick black ink outlines and flat, punchy color blocks reminiscent of Roy Lichtenstein and Andy Warhol. The diver is wearing a high-tech matte teal wetsuit with neon orange accents and a sleek diving mask pushed up onto their forehead, revealing a confident, adventurous expression with bright eyes. The background is a graphic, rhythmic pattern of stylized turquoise ocean bubbles and abstract sea-foam shapes in shades of mustard yellow and magenta. The lighting is artificial and high-contrast, utilizing sharp, hard-edged shadows that define facial features with graphic simplicity. The composition is a centered, symmetrical close-up, maximizing visual impact for a social media avatar profile. Texture is limited to subtle halftone dot patterns applied to the skin tones to mimic vintage comic book print. The overall mood is energetic, playful, and adventurous, rendered with high-fidelity vector-like sharpness and professional digital ink-work.
