Executive-style studio portrait seated on a matte black cube block

Ultra-realistic studio portrait of a man matching the reference face exactly, seated on a low modern matte-black cube block instead of a wooden stool. He leans slightly forward with elbows resting loosely on thighs, hands softly clasped, gaze slightly off-camera for a thoughtful executive vibe. Same outfit: charcoal textured blazer, taupe premium tee, espresso tailored trousers, off-white minimalist sneakers. Studio lighting setup: soft overhead diffused key light with subtle side fill, creating sculpted cheekbones and controlled shadow under jawline. Faint edge light for subject separation. Background: smooth gradient from deep slate grey to charcoal. Focus razor sharp on eyes, shallow depth of field, realistic fabric folds at elbows and knees, natural skin pores visible, no over-retouching, premium magazine editorial style, ultra high resolution. Negative prompt: glossy skin, artificial HDR, harsh facial shadows, busy background.
