    "visualCharacteristics": [
      "Focus on animal figures (bison, horses, deer, mammoths), often depicted with surprising naturalism and vitality",
      "Human figures less common and typically abstract, schematic, or stick-like (distinct from more detailed animal portrayals)",
      "Use of strong contour lines to define forms",
      "Handprints (positive prints or negative stencils) and geometric signs (dots, lines, symbols)",
      "Frequent overlapping of figures, suggesting different time periods or lack of unified composition",
      "Occasional use of natural rock formations integrated into the shape of the animal",
      "General absence of backgrounds, ground lines, or consistent perspective"
    ],
    "techniques": [
      "Simulation of painting/drawing on cave walls",
      "Using natural earth pigments (ochres, charcoal, manganese) possibly mixed with binders",

    "textureEmphasis": "Rough, uneven texture inherent to the natural cave wall surface, often incorporated into the artwork. The paint/pigment itself may appear powdery or stained into the rock.",
    "compositionStyle": "Figures often appear scattered, superimposed, or isolated across the cave surface without a clear compositional structure, ground line, or consistent scale. Arrangement seems opportunistic, utilizing wall contours rather than creating a unified scene.",
