A highly detailed CG unity 8k wallpaper portrait featuring an alluring vampire woman poised to bite the viewer in a shadowy Victorian alley. Her flowing white hair captures the cool glow of the moonlight, contrasting starkly with her tan complexion. She dons a tattered, ethereal dress that seems to whisper secrets from ages past. The scene unfolds under a night sky awash with stars, with a luminous full moon casting an eerie glow. Her mouth is agape, showcasing menacing vampire fangs from which fresh blood trickles. Her predatory gaze is fixed intensely on the viewer, as she crawls towards them in a graceful yet menacing manner. The dramatic lighting accentuates the sharp angles of her face and the glint in her eyes, as if captured by a master artist in the style of Greg Rutkowski.
