Portrait of me sitting on a chair, leaning slightly forward with elbows resting on my knees, fingers interlocked in front of my mouth in a thoughtful, intense pose. My 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 quan.
