Otherworldly Encounter: The Glowing Monolith

Prompt:  Create an illustration with a vintage, painterly style, portraying an alien and a human on a snowy landscape. The alien has a lean, muscular body, standing approximately 7 feet tall with green skin and wearing a snug, violet and indigo bodysuit with a stylized belt. The head is humanoid with large black eyes, pronounced cheekbones, and no visible hair; a round, purple helmet with a transparent face shield partially covers the head. The alien's right hand is raised towards a glowing, monolithic green structure with a smooth, shadow-casting surface. Beside the alien, slightly in the foreground, is a human male with a frightened expression. He's in his late twenties, with short, messy dark hair and pale skin, dressed in a bulky, dark blue winter jacket, jeans, and a red scarf blowing in the wind. In one hand, he's clutching a wooden snow sled. The background is composed of a dense pine forest under a deep blue twilight sky.
