Generate a melancholic portrait of a schoolgirl seated in a dim, minimalistic room. Capture her expressionless, distant gaze, reflecting both youth and an eerie stillness. Employ intricate cross-hatching techniques to create detailed shading on her hair, uniform, and delicate hands, ensuring every fold and crease in the fabric carries depth. The character design should incorporate an unsettling blend of innocence and detachment, with proportions slightly stylized to reflect Gorey's subtle distortion of realism. Keep the background minimal--only a few lines suggest a window frame--allowing the focus to remain on the girl. Integrate symbolic motifs subtly: perhaps a small black cat peeking from the shadows, or the outline of a bird perched outside the window. Use the interplay of light and shadow to emphasize the tension between presence and absence, evoking a sense of quiet discomfort and introspection.
