Chân Dung Nam Chiếu Flash Trực Diện Vào Giờ Xanh

Full-body vertical shot of the young man from the reference photo, standing centered on [a dark rock] at [blue-hour sunset]. He has a calm neutral expression, realistic face with natural skin texture and warm undertones, and [very short dark buzz-cut hair]. Outfit: [solid dark-chocolate brown crewneck sweater] with a smooth non-textured finish, medium-heavy structured fabric, relaxed boxy fit, slightly dropped shoulders, and thick ribbed collar, cuffs, and hem, paired with [loose dark denim jeans] and [black boots]; no hats or head accessories. Lighting: dramatic direct on-camera frontal flash with crisp highlights and hard falloff, cleanly isolating the subject against the twilight environment while preserving rich ambient sky colors. Environment: rugged rocky foreground, subtle silhouetted landscape, expansive evening sky featuring a warm orange and crimson band across the horizon transitioning into deep teal and dark blue, with a faint distant coastline barely visible in the haze.
