robot-portrait in moody portrait-photography

One seated humanoid robot is the single subject, occupying the central area and filling roughly half the frame vertically with the torso and head in center-left third and knees in lower center, framed for a vertical 2:3 crop suitable for a poster-cover. The robot wears a plain dark grey hoodie with visible knit texture, exposed weathered gunmetal faceplate and articulated metal hands resting on an open aged paper-book held at lower-center, with precise mechanical joints, small bolts and subtle surface scratches described. The viewpoint is eye-level, medium portrait shot with tight framing that keeps generous negative space in the upper third for the background wall. Lighting is soft side light from the right with gentle rim highlights on metal edges and warm amber catchlights in the eye cavities, producing deep but soft shadows across the hoodie and couch. Background is an interior sofa and matte plaster wall occupying the upper third with low detail and moderate separation from the subject. Focus renders the robot face and hands crisp while the couch and wall fall to shallow blur, preserving readable paper texture and fabric weave. Render as naturalistic portrait-photography with neutral color balance leaning warm in highlights and cool in shadow, minimal grain, and realistic material reflections on metal without specular overdrive.
