Photorealistic Alien in a Luxury Mansion Foyer

Photorealistic image of an alien in a luxurious mansion interior. In the grand foyer, marble floor, gilded moldings, and a crystal chandelier. A sweeping staircase, heavy drapes, and antique paintings set a regal mood. Centered figure: an extraterrestrial being with a humanoid silhouette, slender frame, elongated head, smooth cool gray-blue skin with subtle bioluminescent specks. The alien has large almond-shaped black eyes, a small mouth, and no visible ears. It wears a tailored midnight blue velvet suit with a high collar and subtle silver piping. The pose is confident, one hand resting on a marble console while the other hangs at the side. Warm chandelier light blends with soft daylight filtering through tall windows, creating long shadows. Use high dynamic range, ultra-realistic textures for velvet, marble, brass, and wood, with a shallow depth of field so the mansion details fade slightly in the background. Camera angle slightly low at about 50mm perspective to convey scale and realism; focus on the alien while keeping the opulent surroundings richly detailed.
