Аниме-школьница в классе со скетч-фоном

Vertical portrait of [a Japanese high school girl] sitting at a classroom desk. The subject is rendered in full-color semi-realistic soft anime style with smooth skin and detailed shading, placed in striking contrast against a black-and-white manga sketch background. Subject details: [long dark brown hair tied in low twin tails with pink hair ties], [large purple eyes], and [a pensive expression]. She wears [a traditional navy blue and white sailor uniform with a red bow tie] and white knee-high socks. Her right hand holds a pen near her temple as she looks down at an open notebook on her grey metal desk; a pencil case sits to her left. Background: other classroom students and desks drawn exclusively in loose greyscale manga line art.
