Photorealistic shot of a MacBook Pro M4 16" in sleek Space Black, positioned open and straight-on, with the blank screen directly facing the camera. The device sits on a polished concrete surface, with soft, natural lighting enhancing its premium metallic finish. The straight-on pose ensures a clean, symmetrical composition, perfect for mockup use. The polished concrete adds an industrial, minimalist touch, with no distractions or angles to detract from the focus on the MacBook and its blank screen. --ar 1:1  --style raw
