Create a square avatar portrait of one adult East Asian man.
Use a straight-on, eye-level head-and-shoulders composition, centered and looking directly at the viewer.
He has warm light olive skin, a narrow mature masculine face, a defined jawline, slightly prominent brow bones, thick natural eyebrows, a straight medium-length nose, thin lips, and subtle tired shadows under the eyes.
His medium-short dark auburn hair is naturally tousled and slightly coarse, with loose waves, irregular forehead strands, deep brown shadows, and restrained muted copper-red highlights.
Keep his own right eyebrow tail fully visible and unobstructed by hair.
His eyes are narrow hazel-brown with subtle olive-green and amber tones.
His expression is quiet, analytical,reserved, and slightly tired.
At the outer tail of his own right eyebrow, appearing on the viewer’s left, there is one short, subtle healed scar line about 3 mm long cutting through the eyebrow hairs.
The scar is confined entirely to the eyebrow area and creates a small visible break in the eyebrow.
It does not extend onto the forehead,eyelid,temple, or cheek.
His only jewelry is one small brass hoop on his own left ear, appearing on the viewer’s right.
No other piercings or earrings.
He wears a dark gray-green work jacket over a plain charcoal-black shirt.
Use soft even studio lighting and a plain light-gray background.
