Prehistoric siblings roasting meat over a campfire

A stylized, anthropomorphic prehistoric boy with messy brown hair, a wide smile, and a curious expression, wearing a loincloth and a beaded necklace, is sitting on a large rock. He holds a stick with a piece of meat roasting over a campfire. Beside him, a prehistoric girl with blonde hair in a messy bun, a stern, slightly annoyed expression, and wearing a fur-like tunic and skirt, is also sitting on a rock. They are in a lush, grassy outdoor environment with a primitive campfire. The background is a soft, muted green. The art style is reminiscent of modern animation, with exaggerated features and a painterly texture. The lighting is soft and diffused, creating a warm, inviting atmosphere despite the characters' expressions. The composition is a medium shot, focusing on the two characters and their interaction. The overall mood is whimsical and adventurous, with a hint of playful sibling rivalry.
