Alien Concept Art in a Haunted House

An otherworldly alien stands in a dilapidated haunted house corridor. The creature is tall and sinewy with pale, slightly translucent skin that glows faintly with bioluminescence. It has large almond shaped black eyes, a tiny slit of a mouth, and long tapering fingers. The scene is moody and atmospheric with cinematic lighting from a flickering candle and a broken chandelier. Dust motes drift in the air, peeling wallpaper, creaking floorboards, and a cracked mirror reflecting a distorted version of the alien. The composition is dynamic with a low angle and leading lines from a decaying staircase. Rendered as high detail digital concept art with painterly textures and matte painting vibes. The color palette combines cool blues and greens with warm amber candlelight. The mood is eerie, mysterious, and unsettling. Subtle sci fi touches include faint glowing runes on the walls and a translucent device on the alien chest hinting at alien technology.
