蜡笔素描混合媒体记忆卡

Transform the uploaded photo into a vertical mixed-media memory card with a strict 50/50 split. Keep the original photo unchanged in the top half. In the bottom half, use textured off-white handmade paper and add a muted, irregular color patch matching the photo's tones. Redraw the main subjects as a simple dark wax-crayon sketch with loose, imperfect lines and minimal details. Add a short handwritten English phrase and subtle Risograph grain. Create a quiet, nostalgic Morandi-style aesthetic with generous negative space. Do not add extra elements or copy the reference composition exactly.
