Sharp geometric portrait of Billie Eilish in elegant black attire

Create a clean, geometric low-poly vector portrait of [CELEBRITY] in the exact style of the reference. Use sharp polygonal facial planes, flat vector shading, subtle gradients, and crisp angular geometry. Keep the portrait centered with a calm, confident expression and a slight three-quarter angle. Dress them in elegant formal clothing (black suit or stylish black outfit depending on the celebrity). Use a soft teal textured background with a subtle vignette. High-detail vector illustration, minimalist, modern editorial poster aesthetic, symmetrical composition, smooth edges, premium quality, 4K, no text, no watermark.
