A man sits in a warm, wood-paneled study, deeply engrossed in a book. The facial features, skin, hair, and body proportions of the subject are inherited directly from the reference image without any alteration, redesign, or replacement. He is seated and leaning back into a plush, worn brown leather armchair on the left-hand side of the frame, his body angled three-quarters to the right. His legs are crossed, with one knee slightly raised. His head is tilted down, with his gaze directed toward the open book held in both hands at chest height. His expression is calm and contemplative, with relaxed brows, a closed mouth, and a quiet sense of relaxed concentration. He wears a soft, brown long-sleeve knit crewneck sweater over a visible white collar, paired with dark blue denim jeans. His hair is neatly combed and styled, following whatever hair the reference person has. A tall floor lamp with a wide, soft white shade on the right casts a warm, golden glow over him and the dark, vertical wood paneling of the room. Shot at eye-level with a medium framing from the waist up. Soft, directional side-lighting creates a gentle gradient of light and shadow, with a shallow depth of field separating him from the softly blurred background. The color palette is composed of tranquil, rich earthy tones of deep brown, bronze, and warm gold. Avoid: altering the face, changing eye or hair color, modifying age, adding or removing facial hair, looking at the camera, standing up, sitting on a modern sofa, book closed, outdoors, bright daylight, multiple people, cold lighting, neon, cartoon rendering, illustration, painterly textures, extra limbs, malformed hands, distorted fingers.
