Lilith is a slender, 1.8m humanoid female with twilight-hued skin exhibiting subtle iridescence and subtle, animated starlight patterns beneath the surface. Her obsidian eyes are deep, reflective pools. She has long, flowing, moonless-night hair and a serene, subtly androgynous face. Instead of wings, two dynamic, inky smoke ribbons unfurl from her back. Her attire consists of minimal, flowing, dark, semi-transparent garments. Key details include subtly pointed ears and delicate fingers. Emphasize fluid motion and ethereal grace in posing and animation, with subtle movements for hair, smoke, and skin patterns. Focus on her insidious beauty rather than overt seduction.
