Create an ethereal, vertical fantasy scene with a large, majestic, deep blue cat-like creature dominating the frame. Its fur has an almost nebulous quality with subtle hints of stars and cosmic dust, suggesting a celestial origin. The cat's eyes are a piercing yet gentle teal, gleaming with intelligence and warmth. Delicate white whiskers stand out against its mystical blue fur. The creature is gazing down, almost nose-to-nose, with a small human girl. The girl, who appears to be in a state of awe or gentle communication with the giant cat, has long, flowing hair reaching down to her waist. She is wearing a simple, dark dress that seems to have a slight shimmer, dotted with tiny, lighter-colored specks resembling distant stars, complimenting the cosmic theme. The background consists of a vast, hazy blue ambiance, softly illuminated as though by starlight, giving a sense of standing in the midst of a calm, peaceful night sky.
