A watercolor illustration of a children's picture book cover. The main subject is a character_appearance. She is action with a white-furred hand. She wears a green garment with a fluffy white collar. The background features soft, painted green foliage and small yellow flowers on textured paper. At the top, large hand-drawn green Japanese text reads "main_title". Below it, brown Japanese text reads "subtitle". On the middle-left, smaller black text reads "author_text". The image has a visible book spine on the left edge, emphasizing the physical book format.
