Shy Anime Guitarist in Sunlit Room

Anime key-visual style square illustration of [Hitori Gotoh], a shy teenage girl with very long straight [pink] hair and blue eyes, blushing with a nervous, downcast expression. She stands indoors wearing an oversized [pink] zip-up tracksuit jacket with pale sleeve stripes and a black skirt. She holds a black single-cut electric guitar featuring gold hardware, cream binding, humbucker pickups, and a black shoulder strap; her left hand grips the guitar neck while her right hand is clutched anxiously near her chest. Soft pink rehearsal room or bedroom interior setting with a mauve-pink wall. Warm sunlight streams in from the right, casting window-frame shadows and a nostalgic glow with soft bokeh dust motes. On the left wall, exactly two items are pinned: one dark concert poster reading "[STARRY]" with smaller band-lineup text beneath, and one small pink sticky note with handwritten Japanese practice notes and a tiny doodle. Faint hand-drawn star and heart outlines accent the wall. Delicate cel shading, glossy hair highlights, and crisp guitar reflections.
