黑白铅笔素描肖像，一位大笑的女性

A detailed black and white pencil sketch portrait of a young woman with a joyful, radiant laugh. She has voluminous, wavy, shoulder-length hair with detailed texture and individual strands capturing a dynamic movement. Her head is turned slightly to the side, showcasing a genuine, wide-open smile that reveals her teeth, with expressive crinkles around her eyes. She is wearing a simple crew neck sweater. The entire drawing is rendered in classic graphite pencil, featuring fine cross-hatching and subtle shading to define her facial features, the soft folds of her clothing, and a softly blurred, lightly sketched background of an indoor room with a window. The entire piece is enclosed within a thin, hand-drawn outer border on textured, off-white sketch paper, evoking a warm, candid, hand-drawn artistic feel.
