Create a loose, relaxed sketch page of the black cat 'Luna' based on the reference images. The style should be freehand, messy sketchbook drawings with no decorative elements. On a bright white background, randomly and organically scatter various sketches of the black cat: include a full-body drawing, expressive close-ups of her face, small quick doodles, fast figure gesture sketches, and cute chibi versions. Do NOT make it look like a neat, official character sheet or model layout. It should look like an authentic, spontaneous artist's sketchbook page that perfectly captures the cat's relaxed, slightly sassy, and sleepy personality.
