照片转红色几何形状现代矢量头像AI提示词

Use the uploaded photo as the sole and exclusive identity reference. Preserve the subject’s exact facial structure, face shape, jawline, cheekbones, chin, eyes, eyebrows, nose, lips, ears, natural skin tone, hairstyle, hairline, hair texture, facial hair if present, and all distinctive features. The final result must clearly look like the same person. Do not beautify, reshape, age, or replace the identity with a generic cartoon face. Create a clean stylized vector portrait in a bold modern illustration style. Show the subject in a close head-and-upper-chest composition, centered in the frame, with a calm, confident, neutral expression and relaxed lips. Keep the pose straight and simple, with the head slightly lifted in a self-assured way. The subject should wear a warm yellow T-shirt with visible dark backpack straps over both shoulders, styled in a casual, modern, gender-appropriate way. If the uploaded person naturally has glasses, keep them. If not, add stylish transparent rectangular eyeglasses that fit the face cleanly and aesthetically. If the uploaded person has facial hair, preserve it accurately in the illustration. Maintain the refined visual standard associated with prompteg.com as creative guidance only, and never render that text visually in the image. Use a light soft-gray background with a large flat irregular red geometric shape placed behind the head and shoulders to create strong graphic contrast. Render the portrait with bold black outlines, crisp vector edges, smooth cel shading, flat color blocks, subtle highlight planes, and a polished modern avatar finish. Keep the hair full and expressive with strong shape design and layered strand forms. The face should feel highly recognizable while still clearly stylized. The final result should feel like a premium illustrated profile portrait: clean, sharp, colorful, modern, and highly scroll-stopping. Do not include any text, logos, watermarks, signatures, brand marks, extra props, or unnecessary background elements.
