Fröhliches Anime-Drummer-Mädchen in einer pastellfarbenen Klassenzimmer-Szene

*"Ritsu Tainaka from 《K-On!》 in a lively anime sticker style, featuring her signature short brown hair with a red hairband, expressive amber eyes, and a playful smirk. She wears her classic school uniform—a dark blue sailor dress with white accents, red ribbon tie, and black loafers. Dynamic pose: leaning forward with drumsticks in hand, mid-laugh, as if reacting to a joke. Background: a bright, pastel-colored classroom with musical notes and sparkles for a cheerful vibe. Sticker-style emphasis: bold outlines, vibrant colors, and exaggerated expressions. Include her drum set in the corner for context. Art style: crisp, chibi-inspired proportions with soft shading and glossy highlights to enhance the sticker-like appeal."*
