An extremely detailed CG unity 8k wallpaper portrait of a mesmerizing vampire woman poised to bite the viewer, set in a Victorian back alley under the haunting glow of a full moon. Her striking white hair cascades around her tan skin, contrasting vividly against the night sky sprinkled with stars. Her mouth is parted to reveal gleaming vampire fangs, with fresh blood delicately dripping down her chin. She wears a tattered, ethereal white dress, shredded at the edges, as she prowls on the cobblestone ground, her eyes locked onto the viewer with an eerie intensity. Dramatic lighting casts deep shadows, enhancing the sinister allure of the scene. The subtle hints of distant lamplights flicker in the misty background, adding an atmospheric depth. The piece is reminiscent of a masterwork by Greg Rutkowski, capturing the beauty and ferocity of the vampire in stunning 8k detail.
