Love Sketch

Use the man and woman from the input photos as the only couple, appearing simultaneously in the background sketch layer and the foreground color photography layer within the same image. Strictly maintain the exact facial features, hairstyle, skin tone, age, and gender across both the upper and lower layers; do not generate two different couples. Create a double-layer art collage of "giant couple pencil sketch + full-color couple photo". The upper background section is a black-and-white pencil sketch portrait taking up most of the upper frame. The woman is on the left, showing a bright, natural smile and winking one eye gently; the man is on the right, close to the woman, with a mischievous smile, raising one hand to his face and lightly pointing his index finger at his cheek. Their heads are close but not overlapping. The sketch features delicate lines with realistic hand-drawn paper texture, with a few simple hand-drawn heart lines around them, but no text. The lower foreground section is a realistic full-color photo of the same couple. The woman stands on the left wearing a brown inner top and a light khaki long blazer, with her long hair falling naturally and hands placed in front of her; the man stands on the right wearing a beige top and a black denim jacket, leaning slightly towards the woman. Both face the camera with natural, relaxed smiles. Reference composition: The two large faces in the background sketch occupy about 55% of the upper frame, and the foreground color couple occupies about 55% of the lower frame, with slight overlap between the two layers. The foreground figures are framed from mid-thigh up, occupying about 70%–80% of the frame width, and must not become a close-up bust shot. The background sketch must be large enough without completely obscuring the foreground subjects. Clear contrast between the full-color foreground and grayscale sketch background, soft studio lighting, realistic skin textures, fine pencil strokes, warm, youthful, and fun couple commemorative portrait style. No titles, text, logos, borders, or watermarks. Avoid inconsistent identities between the two layers, generating four different people, lack of resemblance between sketch faces and real faces, subjects too close, foreground completely blocking the background faces, extra people, extra fingers, or fused facial features.
