A medium shot from a straight-on camera angle depicts a young mermaid with blue hair and striking blue eyes sitting within a human bedroom, looking directly at the viewer. She has a slender human upper body and a shimmering, iridescent blue fish tail that curls naturally on the wooden floor. Her expression is one of curious wonder, with wide, glistening eyes and a slight, soft smile. The room is filled with human artifacts, including a cluttered desk with books, a soft bed with rumpled linen sheets, and a small bedside lamp. The atmosphere is serene and whimsical, illuminated by soft, diffused daylight filtering through sheer curtains, creating a gentle glow and a dreamy, peaceful mood with a pastel color palette.
