Retro 1970s dark anime illustration in Go Nagai's Devilman style. 2D hand-painted animation cell, thick ink linework, heavy shadows. In the foreground, a beautiful, intensely melancholic woman with incredibly long, flowing sea-green hair is floating in zero gravity in deep space, with her legs gently bent towards her body in a graceful, weightless posture. She is shown in profile, leaning her back directly against a large blue planet on the right. She wears a long white silk dress with sea-green shading drifting in space. Her head is tilted backwards, looking up. Her incredibly long sea-green hair flows into the planet, seamlessly dissolving into its glowing atmosphere and clouds. The deep black cosmos is filled with a dense, random scatter of tiny white stardust dots and miniature pinpoint stars. In the upper left, a sinister purple nebula with rich golden gradients and stardust textures fills the pitch-black cosmos. High contrast, gothic, poetic celestial atmosphere. no modern digital art.
