Sleeping Anime Girl in Dark Room

Vertical anime-style illustration of a young woman sleeping peacefully on a bed surrounded by pitch-black darkness. View from a slightly elevated diagonal angle showing her full body curled on her side across rumpled white sheets. She has [dark navy-black] medium-long hair tied loosely in a low ponytail with loose bangs framing her face, closed eyes, soft eyelashes, and a relaxed expression with slightly parted lips. She wears [pale sky blue] long-sleeve button-up pajamas with white piping, a small chest pocket, and matching loose pants, with bare feet visible near the bottom. A thick white blanket is draped over her waist and legs, catching cool blue shadows. Behind her are exactly three visible pink pillows: one large pillow behind her head, one large pillow to the right, and one smaller partially visible pillow farther right. Dramatic low-key lighting with soft highlights on the bedding and face, deep black negative space around the bed, clean ink lines, subtle painterly crosshatching, muted pastel colors, and realistic fabric folds. In the lower right corner, a small handwritten artist signature reads "[HALF_DONE]". No extra furniture, no windows, no lamps.
