Dramatic low-key studio portrait in thoughtful pose

Portrait sitting on a chair, leaning slightly forward with elbows resting on the knees, fingers interlocked in front of the mouth in a thoughtful, intense pose. The gaze is directed straight into the camera, creating a strong, focused presence. Use the uploaded reference image as the primary identity source, strictly preserve facial features, proportions, skin tone, and hairstyle. Do not alter hair type, length, texture, or hairline. The final image must clearly resemble the reference person. Wearing a tight white dress shirt with sleeves rolled up to the elbows, and dark fitted trousers. Forearms must be clean, no tattoos, markings, or skin alterations. Lighting: dramatic low-key lighting with a deep black background. Key light from camera-right, slightly above eye level, creating strong contrast and sculpted shadows across the face and arms. Subtle negative fill on camera-left to deepen shadows, with minimal soft fill near camera for faint catchlights in the eyes. Camera settings: shot on an 85mm lens, f/2.0, ISO 200, 1/125s. Focus: subject sharp with shallow depth of field, background completely black and non-distracting. Texture fidelity: preserve natural skin texture and pores (no plastic smoothing), realistic fabric tension on the shirt, subtle highlights on skin, and clean tonal transitions. Composition: vertical portrait framing, centered subject, tight crop around torso and head, cinematic balance with strong presence. Color & grading: deep blacks with preserved detail, neutral tones, controlled highlights, no clipping. Subtle film grain, clean editorial retouching, high contrast, powerful and introspective mood, premium studio portrait quality. Ratio 4:5
