Shadowed Ninja in an Oil-Painted Pyramid Chamber

An oil painting of a ninja inside a sunlit pyramid chamber. The ninja wears a sleek black cloak with a hood and stands in a poised, agile stance, a katana at his side catching a glint of light. The limestone walls glow in warm ochres and deep umbers, etched with ancient hieroglyphs. Thick impasto brushstrokes render textured stone and flowing fabric, while a single shaft of light pours through a crack in the ceiling, illuminating dust motes and casting dramatic shadows across the ninja's face and cloak. Cinematic chiaroscuro with soft glaze layers provides depth, and hints of gold leaf on the carved runes add a regal glow. Foreground sands sweep toward the viewer; distant shadows imply unseen guardians within the pyramid. Mood: mysterious, heroic, timeless.
