A young woman with deep emerald eyes and a kind, warm smile, wearing a knitted headband, happily hums while polishing a shiny brass horn with a soft cloth in her cozy, sun-drenched attic workshop, filled with stacks of old sheet music and vintage radios. The HiDream-Fast Anime style renders her with soft, blended shading, luminous skin, and clean, defined linework, bathed in a golden, late afternoon light that emphasizes the warmth of the scene.
