Generate a minimal black and white flat vector portrait image of {cristiano ronaldo} in an expressive Notion-avatar aesthetic.Line work and mood:Apply thick, consistent monoline black outlines. The drawing should feel smooth, organic, confident, and hand-crafted 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 aesthetic mostly outline-based, but apply 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 powerful outlines.Layout and technical aesthetic:Center the character as a polished bust or headshot on a white backdrop. Apply only pure black and pure white. No gray, no shading, no gradients, no gentle illumination. The final image should read as high-contrast, crisp 2D vector graphics with a polished avatar-system feel.
