Anime Girl Hugging Orca Plush

Create a polished vertical anime illustration of {argument name="character name" default="a cute teenage girl"} in an aquarium-themed plush shop, shown from the waist up in a close three-quarter view. She has long {argument name="hair color" default="silvery ash-gray"} hair in a low side ponytail tied with one large navy bow, soft bangs framing her face, big sparkling blue eyes, flushed cheeks, and a small open surprised mouth as she looks lovingly at the plush she is holding. She is hugging exactly one oversized black-and-white orca plush toy with pink cheek blush and a tiny red eye; the plush is held diagonally across the left side of the image, with its tail and fins visible. Her outfit has exactly five main visible pieces: a white short-sleeve blouse, a navy sleeveless pinafore-style top, three small gold bow decorations on the front, a gray skirt, and a small beige crossbody bag with thin straps and a clasp resting at her hip. Add exactly two small white hand-drawn heart doodles near her head to show affection. The background is softly blurred and dreamy, filled with pale blue aquarium-shop shelves and rounded sea-creature plushies, with gentle bokeh, pastel blue lighting, and a cozy aquatic atmosphere. Use a high-quality Japanese anime art style with delicate linework, glossy eyes, soft cel shading, subtle fabric folds, warm skin tones, and a bright cute mood. Include a small white artist-handle watermark near the bottom-left reading {argument name="watermark text" default="@minori_chigusa 無断使用NG"}. Keep the composition vertical 2:3, no extra characters, no additional readable text, and emphasize the girl's affectionate expression toward the orca plush.
