Dramatic Green Lantern Comic Portrait

A dramatic comic-book portrait of a {argument name="superhero" default="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. He stands in a shadowy urban alley at night, shown from a slightly low angle in a tight upper-body shot. His hair is short, dark, and windswept, with a strong jawline and intense expression. The lighting is moody and cinematic, with {argument name="lighting highlights" default="warm amber highlights"} on one side of the face and cool green reflections across the suit. The background is mostly black with tall vertical structures and a few bright rectangular lights, creating a gritty nocturnal city atmosphere. Style: modern digital comic illustration, sharp inked contours, painterly shading, subtle texture, rich contrast, {argument name="mood" default="heroic yet brooding mood"}, polished graphic-novel cover art quality.
