Prompt: Imagine a tranquil scene on a public bus during a snowy winter day. Center the composition around a young woman with a serene expression, seated comfortably. She's clad in winter essentials: a thick, woolen overcoat in a muted green hue, a soft-knit beige sweater peeking from underneath, a chunky knit scarf in soft grey wrapped loosely around her neck, and a ribbed-knit beanie in earthy brown tones atop her head. Her hands, adorned with knitted gloves, gently rest on her knee, supporting a large, unembellished skull that stands out against her winter palette with its stark whiteness. The skull should be realistic but not overly decorated, offering a stark contrast to the bundled-up passengers around her, who display a mix of curiosity and indifference. The window beside her frames a wintry landscape, with snowflakes gently falling against the grey sky. The bus interior is warmly lit, casting a cozy glow on the scene. Capture the juxtaposition of the ordinary and the extraordinary, the warmth of winter clothing against the cold skull, and the everyday journey punctuated by an unusual item in tow.
