Create an illustration of two people practicing guitar together. The scene features a girl playing a guitar. She is wearing a school uniform, sitting on a chair, with a serious and calm expression. Her fingers move skillfully across the guitar strings, and she holds a guitar pick. She wears headphones to immerse herself in the music. Beside her, another person is also practicing, their blue skirt, socks, and brown footwear visible. The whole scene is bathed in a permeating light, captured in 8k resolution. Both individuals have detailed faces, and the overall quality of the illustration is a masterpiece --niji 6
