Create a minimalist black and white flat vector portrait of {cristiano ronaldo} in an expressive Notion-avatar style.Line work and mood:Use thick, consistent monoline black outlines. The drawing should feel smooth, organic, confident, and hand-designed rather than stiff, robotic, or generic. Give the character a clear personality with a relaxed, cool, or friendly expression. Emphasize distinctive facial features, hairstyle, facial hair, accessories, and other identity details.Selective black fills:Keep the style mostly outline-based, but use solid black areas deliberately. Fill major dark shapes such as hair masses, beards, eyebrows, sunglasses, or dark clothing. Leave skin, the main face area, and lighter details as pure flat white inside the bold outlines.Composition and technical style:Center the character as a clean bust or headshot on a white background. Use only pure black and pure white. No gray, no shading, no gradients, no soft lighting. The final image should read as high-contrast, crisp 2D vector graphics with a polished avatar-system feel.
