服装：简单纯黑色圆领T恤，肩部和上胸部可见。不戴项链、链饰、吊坠、耳环、眼镜或其他配饰。

背景：纯白背景，头部和肩部后方有一笔大型不规则芥末金色涂绘笔触。笔触边缘粗粝自然，并呈现可见的颜料拖痕，形成醒目对比，但不要遮住脸部。

If a reference photo is provided, use it as the facial identity reference and preserve his facial features, natural skin tone, face shape, hairstyle, eyes, nose, lips, and realistic body proportions.

Create a clean, high-quality digital vector-style illustrated portrait of an adult man, framed from the upper chest upward and facing directly toward the viewer. Use a polished modern avatar/profile-picture aesthetic with crisp outlines, smooth shapes, and detailed hand-drawn shading.

The man has low haircut,  almond-shaped eyes looking directly at the camera, a straight proportional nose, and naturally defined lips with a calm, confident neutral expression.
Use warm natural skin tones with layered cel-shading across the forehead, cheeks, nose, jaw, neck, and around the eyes to create depth while maintaining a clean vector illustration appearance. Define the facial structure with subtle highlights and angular shadow shapes.

Wardrobe: simple plain black crew-neck T-shirt, visible from the shoulders and upper chest. No necklace, chain, pendant, earrings, glasses, or other accessories.

Background: pure white background with a large irregular mustard-gold painted brushstroke positioned behind the head and shoulders. The brushstroke should have rough, organic edges and visible painted streaks, creating a bold contrast without covering the face.

Art style: premium digital vector portrait, semi-realistic cartoon illustration, crisp black linework, smooth cel shading, detailed hair and beard strokes, clean geometric facial shading, sharp edges, balanced symmetry, professional editorial avatar design, vibrant but controlled colors, high detail, polished finish.

Composition: centered and symmetrical head-and-shoulders portrait, direct eye contact, head filling most of the frame, white negative space around the edges, square profile-picture composition, ultra-clean high-resolution digital artwork.
