Create a realistic fantasy image featuring a female High Elf Warlock with white

Create a realistic fantasy image featuring a female High Elf Warlock with white skin, glowing blue eyes, and long, straight black hair. She wears a white corset-style dress with gold details. The front of the dress ends in a short skirt above the knees, while the back features a tail that flows down her right leg, curving around her ankle. She is wearing knee-high white boots with gold accents. The elf stands facing the viewer, her body slightly turned to the left. In her right hand, she forms a glowing purple energy sphere, while in her left hand, she holds a shining obsidian-like black bow. Behind the elf stands a humanoid demon with long reddish horns, torn black robes, semi-folded tattered wings, and a carmine aura. To her left, a crimson red imp hovers in the air. The setting is a carved stone altar on which the characters stand, located in a desolate landscape under a midnight sky with a bright blue full moon. The sky is partially covered with clouds, revealing the Milky Way above.
