Студийный модный портрет в вязаном свитере

Vertical 4:5 photoreal studio portrait of a stylish man in a three-quarter back pose, turning his head over his left shoulder toward the camera with a slight smirk. He has short textured voluminous dark hair, a neat full beard, and rectangular amber-tinted sunglasses with brown frames. He wears an oversized [cream/ivory] chunky-knit sweater with vertical [forest-green] stripes and bold red accent stripes on the sleeves and body, ribbed cuffs and hem, paired with light beige trousers. Mid-torso framing, left arm slightly forward with a simple dark ring on his hand. Seamless bold red backdrop with a soft vignette gradient. Strong key light from camera-left casting a crisp side shadow on the background to camera-right, soft rim lighting on hair and shoulders, warm skin tones, detailed knit fabric texture, high contrast, clean studio aesthetic, no text.
