Carte Souvenir Diptyque en Médias Mixtes

Transform the reference photo into a vertical 4:5 mixed media memory card with a strict 50/50 horizontal split. - Upper half: The reference photo remains completely unchanged, keeping the original subject, composition, lighting, colors, and details, overlaid only with a layer of fine film grain. - Lower half: [warm white handmade paper] texture with visible natural fibers and a soft irregular color spot sampled from the photo's palette. Only the main subject is redrawn as a [minimalist dark crayon sketch] with loose, imperfect lines and subtle Risograph grain texture, accompanied by a [short handwritten English sentence] that fits the mood. Overall style: Quiet, nostalgic, Morandi color tones, tactile, elegant, generous white space. Avoid clutter, decorative borders, stickers, logos, glossy textures, cartoon/vector styling, and any alterations to the upper photo.
