Modern Flat Vector Portrait with Split Teal & Coral Lighting AI Prompt

Create a high-quality modern flat vector-style illustrated portrait based on the uploaded photo while preserving the person's facial identity with 100% accuracy. Maintain the exact facial structure, proportions, hairstyle, beard, moustache, eyebrows, eye shape, expression, and all unique facial characteristics without any alteration. The artwork should feature a clean, contemporary vector illustration style with subtle semi-realistic detailing, sharp outlines, bold geometric shapes, smooth color fills, and a premium graphic poster aesthetic. Use a matte finish with crisp edges, ensuring a polished, professional appearance without visible texture or unnecessary effects. Apply dramatic split-color lighting across the face, with the left side illuminated by cool teal/cyan light and the right side illuminated by warm ochre, coral, or golden-yellow light. Create strong contrast with bold highlights and deep, well-defined shadows while keeping the lighting clean and consistent. Avoid excessive gradients, color bleeding, or soft transitions. Render the hair with stylish volume using clean vector strokes, and emphasize a sharp jawline, well-defined beard and moustache, expressive eyes, detailed eyebrows, and crisp facial contours. Compose the portrait as a head-and-shoulders illustration with the subject positioned at a subtle three-quarter angle, naturally looking to the side rather than directly at the camera. Center the composition and place a perfectly circular graphic backdrop behind the head featuring a smooth gradient that transitions from blue on the left to red on the right. Surround this with a flat, dark navy or deep blue outer background that remains clean, minimal, and free of noise or distracting elements. Produce an ultra-high-resolution vector poster with razor-sharp edges, balanced proportions, and flawless graphic quality. Do not modify the subject's facial identity, pose, lighting direction, color palette, hairstyle, or overall composition. Do not add extra objects, accessories, text, effects, photorealistic skin texture, blur, distortion, or any elements that alter the original concept.
