Smart Casual Menswear Indoor Lifestyle Portrait

Create a full-body professional lifestyle fashion photograph of a handsome man with natural hair, and dark sunglasses with thin metal frames, sitting relaxed in a mid-century modern armchair with a solid walnut wood frame and cream boucle/linen upholstered cushions.
Outfit: Deep blue linen long-sleeve button-up shirt with sleeves rolled up, top two buttons undone, worn untucked; paired with off-white/ivory relaxed-fit linen trousers; white airforce sneakers; a gold-tone wristwatch on the left wrist.
Pose: Seated upright in the chair, body angled slightly away from camera, right leg crossed over the left leg, both hand resting casually near the knee, back relaxed against the cushion, giving an effortless, confident lounging posture.
Expression: Calm, composed, expression and gazing off-frame to the left, conveying quiet confidence rather than direct eye contact.
Background: Softly blurred warm beige interior setting suggestive of a modern living room — a tall potted areca palm on the right, a built-in wall shelf with a decorative ceramic vase, books and dried flowers on the left, shelf lighting creating a warm glow, plain taupe wall paneling behind.
Lighting: Soft, diffused natural light coming from the upper left, creating gentle directional shadows on the wall and floor (venetian-blind style light streaks), warm color temperature, soft fill light reducing harsh contrast.
Camera angle: Eye-level to slightly elevated three-quarter angle, full-body shot, vertical/portrait orientation, shallow depth of field with the subject in sharp focus and background softly out of focus (bokeh).
Technical details: Shot on a full-frame DSLR/mirrorless camera, 50mm prime lens, aperture f/2, ISO 100–200, natural color grading with warm neutral tones, high resolution, commercial fashion editorial style, clean and minimal aesthetic.
Aspect ratio 4:5.
Negative prompt: no feet crop, low quality, blurry, distorted face, plastic skin, bad anatomy, lighting error, deformed hands, warped phone, duplicated objects, no unnatural pose error, harsh shadows, cluttered background.
