에메랄드 슈퍼히어로 코믹북 포트레이트

A dramatic comic-book portrait of a [stern male superhero] in a dark emerald suit with a high collar, a sleek black-and-green eye mask, and a glowing circular chest emblem. Standing in a shadowy urban alley at night, shown from a slightly low angle in a tight upper-body shot. Short, dark, windswept hair, strong jawline, and an intense expression. Moody and cinematic lighting with [warm amber highlights] on one side of the face and cool green reflections across the suit. Background features deep shadows, tall vertical city silhouettes, and distant rectangular window lights. Style: modern digital comic illustration, sharp inked contours, painterly shading, rich contrast, and polished graphic-novel cover quality with a [heroic yet brooding mood].
