Green Field Tree Walk

Use my uploaded photo as the exact face reference. Keep my face, hairstyle, skin tone, body proportions, and identity 100% unchanged. Place me naturally walking along the narrow green grass path beside the beautiful tree shown in the reference image. I walk slowly while looking directly toward the camera with a soft confident smile. One hand remains inside my pocket and the other swings naturally while walking. I wear a white Mandarin full-sleeve shirt with folded sleeves, black pants, and white sneakers. Match every lighting detail, shadows, reflections, colors, and HDR exactly with the original background. Ultra-realistic DSLR photography, 85mm lens, cinematic HDR, shallow depth of field, premium quality, 16K.
