character: hatsune_miku. In an empty classroom after school signaling the start of summer vacation, hatsune_miku sits on a wooden desk positioned center-frame in a medium shot from a slight low angle. She is dressed in a school uniform consisting of a white collared short-sleeved shirt with detached sleeves, navy necktie, pleated skirt, and black knee-high socks. Her very long aqua twintails cascade down her back, adorned with black hair ribbons. With long legs elegantly crossed, her left hand grips the edge of the desk while her right hand rests on her knee; she turns her head to gaze thoughtfully out the large open window to her right, her blue eyes narrowed in a determined expression as she ponders her decision. The classroom features scattered desks, chairs, and fluttering curtains in the warm sunset light streaming through the window, casting golden highlights and long shadows with detailed shading. Anime-style illustration in manga aesthetic, high contrast, intricate linework, great quality rendering of textures like wood grain and fabric folds, serene and introspective atmosphere.
