A female superhero in a trench coat style, wearing a blue tight-fitting battle suit and a brown trench coat, revealing only her torso and legs, holding a blue paper cup in her hand. The background is a rough dark blue wall. The color palette consists of blue, brown, red, and gold, creating a warm-cool contrast overall. The composition uses a vertical half-body cut, with the figure positioned to the right. The lighting is soft and even, with a delicate texture of the trench coat. The atmosphere conveys a sense of urban secrecy and casual everyday life. The style is realistic digital painting, resembling a movie promotional poster.
