Young woman with messy bun smiles gently in a pencil sketch

A highly detailed pencil sketch portrait of a young woman with a warm, gentle smile, resting her chin softly on her hand. Her hair is styled in a messy high bun with loose, delicate strands framing her face. She has large, expressive eyes, long eyelashes, and well-defined eyebrows. She is wearing a cozy, textured knit sweater with ribbed cuffs. The artwork features fine cross-hatching and shading, capturing a soft and intimate atmosphere on light-textured paper, complete with a tiny, subtle hand-drawn heart accent in the background.
