Ancient Stone Age Anime Blacksmith at the Forge

An epic anime-style illustration of a Stone Age blacksmith at a primitive forge. The rugged smith, with spiky hair and a fur cloak over a leather apron, wields a stone hammer and pounds glowing ore on a rough stone anvil. Sparks fly as the metal heats in a clay-and-stone furnace; bones and flint chisels lie nearby. The background shows a cave wall and primitive huts with thatch; warm orange firelight contrasts with smoky blue shadows. Dramatic lighting, dynamic action lines, and sharp anime-style eyes on the determined smith. Tribal patterns etched on the metal and on the smith's skin; overall mood is gritty, heroic, and fantastical with high detail and vibrant color.
