Cartoon caveman couple by a glowing hearth in cave

A cartoonish, slightly eerie illustration of a caveman and his woman sitting by a glowing hearth inside a cave, a mammoth hide draped nearby and prehistoric wall paintings in the background; exaggerated expressive features, vibrant saturated colors, visible pencil strokes and sketchy lines, textured stone and fur details, playful yet uncanny mood, emphasize stylized anatomy, primitive tools and artifacts, cozy but mysterious cave interior.
