Maintain facial proportions, hairstyle (long dark hair with volume), and the blowing-kiss gesture toward camera (hand lifted near lips, eyes closed, lips puckered). Keep the strapless red satin dress silhouette and gold jewelry. Maintain the clean white wall background and strong direct-flash aesthetic with a crisp shadow behind her. Improve realism only: natural skin texture, accurate satin highlights, correct anatomy. No text, no logos, no watermark."
