She looks upward with a playful expression while leaning slightly toward the camera. The bubbles are large and iridescent (rainbow reflections), floating across the foreground and right side of frame. Background is a lush green garden with trees, leaves, and soft depth-of-field blur. Natural daylight, soft and clean, realistic skin texture and pores, mild freckles, no beauty filter.",
