manhwa style, frontal portrait shot, the character from the reference images wearing his round black-rimmed glasses and grey hoodie. He is holding a black assault rifle close to his chest, arms visible. He is standing still, looking directly at the camera with a calm, stoic, completely emotionless facial expression, blank dead eyes staring at the viewer. Menacing zombie apocalypse atmosphere, dark webtoon aesthetic, solid white background, clean line art
