A stunningly detailed CG unity 8k wallpaper portrait showcases a haunting vampire woman poised to bite the viewer in a dimly lit Victorian back alley. Her striking white hair cascades down, contrasting with her alluring tan skin. She wears a tattered, ghostly white gown, intricately ripped, giving a glimpse of her graceful yet predatory form as she crawls menacingly towards the viewer. Her mouth is agape, revealing sharp, glistening vampire fangs with fresh blood trickling down her chin. The scene is illuminated by dramatic, chiaroscuro lighting that enhances the moonlit atmosphere of the alley. Above, the night sky twinkles with stars under a resplendent full moon. Her piercing eyes lock onto the viewer, creating an intense and captivating connection. The art style embodies the dark fantasy vision of Greg Rutkowski, with small twists in her expression and setting that evoke an eerie yet irresistibly alluring aura.
