Semi-Real Anime Girl in Sketch Classroom

A vertical portrait of a cute Japanese high school girl sitting at a desk in a classroom. The subject is rendered in a semi-realistic, soft anime style with smooth skin and detailed shading, while the background is depicted as a black-and-white manga sketch. She has 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 (seifuku) 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 the grey metal desk. A pencil case sits on the desk to her left. In the background, other students are visible but drawn only in greyscale line art, creating a striking contrast between the colored foreground character and the monochrome environment.
