Realistic Professional Avatar Prompt

Generate a real, natural, and approachable professional headshot based on the input photo, highly maintaining identity consistency, facial proportions, face shape, hairline, age perception, and original gender expression without changing appearance. 1:1 square composition, framed from chest up, using asymmetric visual balance: subject slightly right, retaining about 18% headroom, left and top-left forming main negative space, avoiding ID-photo centering and tight cropping. Natural shoulder line, slight head tilt, looking directly at camera, relaxed, confident, friendly expression, natural smile or toothy smile allowed.

Clothing is simple dark round-neck or minimalist top, naturally adapted to the person's original style; females retain natural hairstyle, makeup, and moderate jewelry; males retain stubble, hairstyle, and other realistic features, no stereotypical gender styling. Background is a real warm-toned wall: low-brightness red-brown/caramel warm gray at top, gray-beige/apricot in middle, cream-white at bottom, forming non-linear vertical gradient via natural light falloff, wall reflection, and slight vignette; add fine, low-amplitude, high-frequency random noise, more obvious in shadows, simulating early digital sensors and slight JPEG texture.

Use large-area soft window light, low lighting ratio, low local contrast, no rim light or commercial studio shaping. Skin tone maintains real hue differences and natural blood color; females avoid porcelain skin smoothing, males avoid over-emphasizing rough texture; reduce high-frequency skin details and clarity, retain mid-low frequency facial structure, making skin soft but real. Overall low-saturation warm tone, soft highlights, slight lift in blacks, reduced blue-cyan tones, presenting 2000s–2010s early digital headshot quality: smart, trustworthy, relaxed, natural, approachable, rather than modern high-end commercial portrait.
