Upper half: an intimate close-up profile-to-profile shot where the woman (left) and man (right) face each other at very close distance, calm emotional expressions, shallow depth of field, soft natural daylight. Their faces must match the uploaded references exactly with realistic skin texture. Styling: soft winter palette; the man wears a beige/tan coat with a ribbed turtleneck sweater; the woman wears a muted red coat or scarf accent, short natural hair. Lower half: a serene winter lakeside scene with a small modern lake house on stilts over the water, muted sky, bare trees, and a classic red mailbox in the foreground on the left. A clean white horizontal band separates the two halves and provides space for the title. Overall tone: wistful, gentle, timeless romance; premium poster composite, print-ready.",
