Portada de Libro Infantil en Acuarela

A watercolor illustration of a children's picture book cover. The main subject is a [cute furry kemonomimi girl with short green hair, cat ears, and green eyes], who is [smiling happily while holding up her middle finger] with a white-furred paw hand. She wears a green garment with a fluffy white collar. Background of soft painted green foliage and small yellow flowers on textured watercolor paper. At the top, large hand-drawn green Japanese text reads "[なかゆびさん]". Below it, brown Japanese text reads "[こんにちは]". On the middle-left, smaller black text reads "[さく・え：とらの]". The left edge shows a visible book spine, emphasizing a physical hardcover book format.
