In the extreme foreground, a hand holds two classic red-and-white striped candy canes arranged into a heart shape, framing the couple in the center of the heart. The candy canes and the hand are close to the lens and slightly out of focus (creamy foreground blur). The couple stands several meters behind, in sharp focus, embracing intimately. The man gently kisses the woman’s forehead; she smiles softly with eyes closed. Light snow is falling, with a few snowflakes visible mid-air. The ground is covered in fresh snow and the tall pine trees behind them are heavily snow-laden.\n\nWardrobe & styling:\n- Cozy winter knitwear: cream/white sweaters with subtle patterns, winter beanies (neutral tones), jeans; wa
