"December Spleen" is a realistic painting depicting a solitary woman against the backdrop of a blurred, nighttime city street. Her closed eyes and slightly bowed head suggest introspection and emotional withdrawal. The scattered streetlights form soft, almost abstract shapes, enhancing the sense of isolation. The dark tones of the background, infused with the chill of the winter air, amplify the feeling of nostalgia and quiet sorrow, creating an image filled with subtle emotions and reflection.
