Digital Comic Illustration Upper Body Pose

Prompt 1

Create a square 2x2 digital comic-book grid containing four distinct adult male characters, one upper-body character per panel. Top left: a serious bespectacled man with short brown hair and a moustache, green shirt, and dark jacket on a green background. Top right: a stern long-haired man with a short beard in a black suit and dark tie on a light gray background. Bottom left: a clean-cut blond superhero in a blue suit with red and gold details and a red cape on a blue background. Bottom right: a menacing clown-like villain with white face makeup, dark eyes, red lips, green hair, a purple coat, and green vest on a purple background. Use bold black ink outlines, saturated flat colors, hard comic shadows, clean panel borders, subtle hand-drawn motion lines, and sharp graphic-novel rendering.
