Photorealistic back view of a beautiful woman with blonde hair tied in a high ponytail, completely naked, kneeling on a low stool against a dark tiled wall. She is intricately bound in an extreme and artistic Japanese shibari rope bondage, complex rope patterns wrapping around her arms, wrists tightly bound behind her back, multiple ropes across her torso and shoulders. Numerous long wooden sticks are inserted through the ropes creating a dramatic sunburst or porcupine pattern radiating from her upper back. Her back is arched, buttocks prominently displayed, bare feet visible. Moody cinematic lighting with strong contrast, subtle highlights on her skin and ropes, dark blue-gray tiled background. Ultra realistic skin texture, detailed rope and knot textures, realistic muscle tension, dramatic shadows, sensual and artistic atmosphere, 8k, photorealistic, masterpiece, shot on 85mm lens
