Chân Dung Low-Key Chàng Trai Trầm Tư

A dark, moody, photorealistic portrait of [a young man in his early 20s, slim face, pale skin, soft sharp jawline, messy medium-length wavy dark hair partially covering his forehead]. He is seated on a simple wooden chair, body slightly turned sideways, head tilted downward, eyes cast toward his hands in a contemplative, melancholic expression. He wears [a black high-neck turtleneck under a long black overcoat in soft matte fabric]. Background: rough, textured wall with subtle stains and uneven paint in desaturated green-gray tones. Composition: medium shot, slightly off-center framing. Lighting: extremely low-key soft side lighting from the left, casting deep shadows that partially obscure facial features while leaving them faintly visible. Style & Texture: raw cinematic analog aesthetic, heavy film grain, visible noise artifacts, subtle motion softness, muted color palette, realistic proportions, no digital over-sharpening or artificial stylization.
