Hyper-detailed graphite portrait of sleeping woman with void tunnels

A hyper-detailed graphite portrait of a sleeping woman on a rumpled pillow; the left side of her face peels open into perfectly concentric tunnels that recede to a pitch-black void. Fine pencil cross-hatching defines skin texture, subtle hair strands drape over the pillow, and the void's inner walls display geological-style ring shading. Style: photoreal graphite surrealism Aspect ratio: 3:4 Negative prompt: text, watermarks, harsh digital noise, exaggerated cartoon lines Lighting: soft diffuse bedside lamp from camera left Composition: tight three-quarter portrait, face void aligned on golden ratio point Color palette: monochrome silver-gray graphite tones
