Do not crop the image in a way that cuts off any part of the 18-year-old girl's body. Avoid framing the image so that only her face and upper body are visible. Do not allow the towering bookshelves to obscure her lower body. Ensure that her arms and legs are not cut off at the edges of the image, and the full length of her figure, from head to toe, should be entirely within view. The picture should not zoom in too close, preventing a full-body portrayal within the grand library setting.
