Regal high-society elegant slender lady, draped in opulent attire, shrouded in glistening, translucent, metallic-tinged slime-foil layers, accentuating her haughty demeanor, adorned with sleek, silver, stiletto heels and an otherworldly, bioluminescent mind control headband, reclines on black, glossy, slime-encrusted pillows within an ancient Egyptian sarcophagus, enveloped by a transparent, glistening slime ceiling, situated at the heart of a mystical, subterranean cavern, surrounded by sinuous, pulsing tentacles, as a colossal, swirling portal to the cosmos looms in the background, shrouded by a labyrinthine network of iridescent slime webs, wispy fog wafts from the polished, steel floor, illuminated by the faint, crimson glow of a macabre, lunar eclipse, evoking a sense of foreboding, inspired by the dark, biomechanical, surrealistic style of H.R. Giger and the epic, cinematic grandeur of Steven Spielberg, with the gritty, high-contrast aesthetic of a 35mm film still, shot on a v-raptor XL camera, with pronounced film grain, vignette, and a rich, cinematic color palette, post-processed to perfection, exuding an atmosphere of eerie, sci-fi horror.
