In the city of Simitli, Bulgaria, a spiral-bound sketchbook rests on a dark brown wooden surface, illuminated by artificial light. The sketchbook, angled slightly from the viewer's perspective, displays a detailed, predominantly grayscale pencil drawing on a white page. The drawing depicts a winged, partially nude female figure, possibly an angel, centrally positioned within a dark, cavernous environment. Her torso is bare, with breasts visible. She appears to be suspended or impaled, with a slender rod-like object passing through her midsection, and heavy chains securing her lower body. One prominent feathered wing is visible on her left, while the right wing is partially obscured. Her dark hair flows, partially obscuring her face. Below and to the right of the female figure, a horned, demonic-like creature with a long tail is partially visible. In the upper right background, a disembodied hand reaches or struggles within a dark opening in the rock-like wall. The drawing features cross-hatching and shading, with minimal brown tones accentuating certain elements of the demonic figure and shadows. The dark wooden surface surrounding the sketchbook reflects the ambient light, showing subtle grain patterns.
