Keep the person's face 100% identical to the original photo. Preserve every facial feature exactly: the shape and spacing of the eyes, the nose, the lips and mouth, the jawline, cheekbones, eyebrows, skin tone, and the overall face structure and proportions. Do NOT beautify, smooth, slim, reshape, retouch, or alter the face, age, or expression in any way. Only change [describe what you want changed - e.g. the background, the clothing, the lighting]. The tace and head must remain exactly as in the source image.
