Create a spine-chilling Halloween masterpiece with an 8k resolution

Create a spine-chilling Halloween masterpiece with an 8k resolution. The artwork should feature a witch with long, silverly-white hair down to her knees, adorned with red demonic tattoos on both arms. She's totally and completely naked, wearing nothing, bare body, (pink areola, deep-pink nipples, vaginal rundown), with a sadistic and creepy smile on her lips. Her eyes are large, pale, and red in color. The witch is on her knees, blood dripping from her hands as she is performing a satanic ritual by drawing demonic patterns with blood, piles of skulls and bones are at the corners of an extremely dark room with the back window open, candles are the only light source, a blood-red crescent moon visible, a broken castle on the left side, and a cemetery on the left side. The scene should be set in a dark, abandoned castle under the moonlight, with demonic patterns drawn with blood on the ground. The design should be dark, scary, and highly detailed, with sharp focus and a realistic look. Utilize Octane render with maximum clarity, sharpness, and hyper-realistic horror-movie style light and shadow (1.2) along with depth of field for added impact. Naked, ((NSFW)), vaginal rundown, pubic hair.
