Watercolor Children Picture Book Cover Featuring Cute Green Haired Cat Eared Kemonomimi Girl Friendly Wave

High-quality whimsical watercolor children's picture book cover illustration, textured cold-press watercolor paper base, soft warm natural lighting, gentle muted pastel color palette, sharp crisp details.

Main subject: a cute original kemonomimi young adventurer with short green hair, cat ears, green eyes, and a soft white-furred hand, smiling happily while giving a friendly wave, wearing a loose green garment with a fluffy thick white fur collar.

Background: soft blended painted lush green foliage scattered with tiny bright yellow wildflowers, shallow depth of field to keep focus on the central character.

Text elements, all hand-drawn, legible, matching the cozy illustration style: large bold green Japanese text at the very top of the cover reads "もりのともだち", smaller hand-drawn brown Japanese text directly below the main title reads "こねこの小さな冒険", small hand-drawn black Japanese text on the middle-left reads "作・絵：みどり".

Physical book details: full visible illustrated book spine runs along the entire left edge of the frame, subtle soft drop shadow under the book to emphasize its physical printed format, no distorted or misprinted text, overall cozy playful children's book aesthetic. No logos, no copyrighted characters, no watermark.
