忧郁吉他少女与猫

Create a wide minimalist anime illustration with abundant empty negative space on the left and the main subject placed on the right. Show a quiet teenage girl in full body side profile facing left, with {argument name="hair color" default="dark navy-black"} short bob hair, blunt bangs, pale skin, and a calm melancholic expression. She wears an oversized dark hooded jacket over a dark plaid school-uniform style outfit, a short pleated plaid skirt, black fishnet tights with a small black garter bow on one thigh, and chunky black platform shoes. A tall dark guitar gig bag is strapped vertically on her back, extending above her head. In one relaxed hand she holds a smartphone. At her feet sits exactly 1 black cat in silhouette, looking up at her. Use a soft off-white background with pale blue-gray watercolor cloud washes behind the figures, delicate ink linework, muted blue-green shadows, subtle cel shading, airy composition, quiet indie music mood, high-detail anime key visual style, no text, no border.
