Grauer Alien in Kapuzenjacke mit Kampfstiefeln

A realistic, black and white illustration of a classic grey alien standing with its hands in the pockets of a beige, hooded, multi-pocket jacket. The alien has a large, bald head with massive, dark, almond-shaped eyes and minimal facial features except for a small nose and mouth. It wears a grey t-shirt underneath the jacket, and appears to have a black backpack slung over its shoulders. Its extremely thin legs are visible below the jacket, ending in rugged, lace-up combat boots. The illustration style is detailed line art with a grainy texture, reminiscent of vintage comic books or concept art. The background is solid black, emphasizing the subject. The lighting is dramatic and high-contrast, highlighting the textures and form of the alien and its clothing. The composition is a full-body portrait, centered and facing forward, creating a direct and slightly imposing gaze. The mood is one of mysterious stoicism and urban cool.
